Well, you don't know it now, but you just asked the meaning of life.
I've got a somewhat incomplete version 2.0 of my Priority essay that never saw the light of day since the ARRJ was never published with it. It's not 100% accurate, but of course, anything that helps you understand what priority is in the long run will help you figure out priority questions on your own, priority really isn't that hard to explain, but to explain the different scenerios, when a player has priority or not, that's a different story.
Here's the Version 2.0 that never got posted, I'm not proud of it to be honest, I wanted to make edits to it before I ever posted it somewhere, but I never found time to do those edits, it'll seemed rush, mainly because it was rushed, wrote in about a day or 2 under a deadline that never meant anything since the ARRJ was never put online.
But I hope it answers your questions.
Priority 2.0
By: Michael Palmer
Priority is a touchy subject for any judge to address. With the fact that there is very few known details on how priority actually works and the actual game mechanic of the entire system, it makes it hard for even the best of judges to make the right call on it. With the rumors of the upcoming "Priority Essay" coming from the UDE Game Developer himself, Kevin Tewart, one can only wonder if we've been doing things right all along, or if we've been so wrong that it's not even funny. Well, with all this said and done, I decided two months ago to write an article that pertained to priority and nothing but priority. The article got great reviews from people who were glad that things were finally explained. I decided to update the original article with new information and more in depth descriptions on the workings of most rulings that involve priority, once again, many thanks and praise came from the readers, but much discussion was raised as well, with it seemingly split down the middle, we had people arguing whether priority only pertained to the summoned monster, or the entire playing field and state of the game at the time of the chain events. With Yu-Gi-Oh! not being an event driven game like most other games, it makes it much more difficult to know who was right and who was wrong.
With all this set aside, I've compiled what I feel is the most accurate description of priority and the cards that may be involved in just about every aspect of it in this article, the third installment of the Priority Essay from Netrepâ„¢ Net. Thank you for reading this far, now I hope you learn and enjoy the facts, controversies, and rulings that you face ahead.
Also, before I get started, I'd like to remind everyone of the golden rule of priority"¦ That rule is "YOU THE PLAYER HAVE PRIORITY, NOT THE MONSTER!" With that in mind, let's continue.
To start off this article, I thought I'd start it off like I did with every other article with the explanation of "
Tribe-Infecting Virus" Vs. "
Bottomless Trap Hole"/"
Trap Hole"/etc. The first chain of events I'm showing you will always be how it's being played, the current gameplay is considered to be "incorrect" and regardless of the matters at hand, many people feel I should explain how it should be played because the opposing player is always playing out of turn when the wish to use priority to activate a monster's effect is declared, so it is always wise to ask your opponent when they summon a monster "Do you wish to activate that effect?" and if they say "No" then they pass their priority to you to activate your trap card, if they say "Yes" then they may activate their effect and then you may activate you trap card in a chain to the effect. The second chain of events is the chain events that you should pay attention to if you are indeed playing your cards wrong. First the incorrect:
Player A summons "
Tribe-Infecting Virus" to the field.
Player B responds with "
Trap Hole".
Player A chooses to use turn priority to activate Tribe's effect in a response chain.
Player B's "
Trap Hole" is then added on the chain as link 2.
Now the correct:
Player A summons "
Tribe-Infecting Virus" to the field.
Player B asks Player A "Do you wish to use "˜
Tribe-Infecting Virus'' effect?"
Player A answers "Yes" and activates "
Tribe-Infecting Virus'" effect by discarding a card and announcing a type.
Player B chains the activation of the effect with "
Trap Hole" to destroy "
Tribe-Infecting Virus".
Chain:
Link 1: "
Tribe-Infecting Virus'" effect is activated.
Link 2: "
Trap Hole" is activated.
Resolution:
Link 2: "
Trap Hole" resolves first since it was the last card on the chain and destroys "
Tribe-Infecting Virus".
Link 1: Then Tribe's effect resolves since it was not negated destroying all monsters of the specific type called.
Reason: I know what many of you are thinking. How can a card resolve fully if it's no longer present on the field at resolution? Well, to put it quite simply, it's like chaining MST to "
Raigeki". Even though you destroyed "
Raigeki" in the chain, it's effect was never negated so it will resolve as normal even though it was destroyed in the resolution step before it's resolution would take place. The same goes with Tribe and any other monster, its effect is being chained to with the trap card being responded with. Since you can't chain to the summon, the trap card would have to be chained to the cost effect of the monster. Since the cost effect is spell speed 1, it would have to be the first link in the chain. Then you add on the speed 2 effect of the trap card, in this case it was "
Trap Hole", and it destroy Tribe first and then Tribe's effect destroys all monsters of the specific type called.
Incorrect:
Player A summons "
Magical Scientist".
Player B activates "
Ring of Destruction".
Player A uses turn priority to activate "
Magical Scientist's" effect by paying 1000 Life Points and targeting a fusion monster in his/her fusion deck.
Correct:
Player A summons "
Magical Scientist".
Player B asks Player A "Do you wish to activate "˜
Magical Scientist's' effect?"
Player A responds with "Yes" and activates "
Magical Scientist's" effect by paying 1000 Life Points and targeting a fusion monster in his fusion deck.
Player B chains the activation of "
Magical Scientist's" effect with "
Ring of Destruction".
Chain:
Link 1: "
Magical Scientist's" effect is activated.
Link 2: "
Ring of Destruction" is activated.
Resolution:
Link 2: "
Ring of Destruction" resolves destroying "
Magical Scientist" and dealing 300 points of damage to both players.
Link 1: "
Magical Scientist's" effect resolves special summoning a Fusion monster.
Reason: Basically this is the same as "
Tribe-Infecting Virus". With the effect of "
Magical Scientist" being spell speed 1, there is no way it can go on any other spot on the chain but the first link. You can't chain a speed 1 effect to a speed 2 or even speed 1 card for that matter it can't be chained to anything, except in the response chain of priority. The effect of "
Magical Scientist" would resolve after "
Ring of Destruction" destroyed it because there was no negation of the "
Magical Scientist's" effect during the chain.
Incorrect:
Player A summons "
Magical Scientist".
Player B activates "
Torrential Tribute".
Player A uses turn priority to activate "
Magical Scientist's" effect and targets "
Mokey Mokey King" in his fusion deck.
Correct:
Player A summons "
Magical Scientist".
Player B asks Player A "Do you wish to activate "˜
Magical Scientist's' effect?"
Player A says "Yes" and activates the effect by paying 1000 Life Points and targeting "
Mokey Mokey King" in his fusion deck.
Player B chains the effect with "
Torrential Tribute".
Chain:
Link 1: "
Magical Scientist's" is activated targeting "
Mokey Mokey King" in the fusion deck.
Link 2: "
Torrential Tribute" is activated.
Resolution:
Link 2: "
Torrential Tribute" resolves destroying all monsters on the field.
Link 1: "
Magical Scientist's" effect resolves special summoning "
Mokey Mokey King" from the fusion deck.
Reason: Well, this one should be a little obvious after you read over the first two, but I thought it would be good to note this since it shows something that is pretty interesting. "
Magical Scientist" was used to special a monster in response to "
Torrential Tribute". How most assumed this would work out at first when these cards first faced each other in play, it was thought that the special summoned monster from the fusion deck would be destroyed as well, but after further looking at the chain later, many people realized that the monster would be special summoned after "
Torrential Tribute" resolved, therefore leading to the fact that Player A now has one monster on the field after the chain and that is the special summoned fusion monster. Just something I thought would be interesting to note.
Player B has "
Skill Drain" face-up on the field.
Player A tribute summons "
Jinzo".
Player B's "
Skill Drain" is already active and is a continuous effect.
Player A's "
Jinzo" is negated upon the successful summoning.
With this it's a simple time stamp effect. Since "
Skill Drain" was in effect first on the field, "
Jinzo's" effect is negated.
Player B has a face up "
Level Limit - Area B" on the field.
Player A tribute summons "
Spell Canceller".
Same issue as above, since Level Limit was in effect first, it will turn "
Spell Canceller" to defense position. Then "
Spell Canceller's" effect will trigger, negating Level Limit, I'll also add to this, since Level Limit is negated that DOES NOT mean you can change the position of "
Spell Canceller", you can not change the positions of a monster summoned that same turn, so it'll stay in defense until it's either destroyed or until you can turn it your next turn. You however can change the positions any other monsters you may control at that time since "
Spell Canceller" has now negated Level Limit.
Reason: The above explanations show to you that a time stamp can determine priority of effects in this game. Since "
Skill Drain" was in effect before "
Jinzo" was summoned to the field, it will negate "
Jinzo" before "
Jinzo's" effect can become present to negate "
Skill Drain". A similar situation applies to "
Spell Canceller" Vs. "Level Limit "“ Area B", since "Level Limit "“ Area B" was in effect before "
Spell Canceller" was summoned, it would switch "
Spell Canceller" first, then the effect of "
Spell Canceller" would trigger negating "Level Limit "“ Area B". Hope that helps in any confusion you may have had over this situation.
Player A tribute summons "
Mobius the Frost Monarch" and targets two spell/trap cards on the field.
Player B responds with "
Torrential Tribute".
Chain:
Link 1: Mobius' effect is activated targeting up two spell/trap cards on the field.
Link 2: "
Torrential Tribute" is activated.
Resolution:
Link 2: "
Torrential Tribute" resolves destroying all monsters on the field.
Link 1: Mobius' effect resolves destroying the two spell/trap cards that were designated as the targets upon activation (summoning).
Reason: This one should be apparent, the effect activates as soon as it's summoned, and this means that as soon as Mobius hits the field, the player controlling Mobius gets to select up to two targets with it's effect. Then Player B has the right to respond with a trap after the selection is made. Mobius' effect would resolve as normal and than the trap card activated in response to him will resolve as normal.
Player A's "
D. D. Warrior Lady" attacks Player B's Face Down Card.
Player B flips their Face Down Card and reveals their own "
D. D. Warrior Lady".
Damage Calculation is reached and Player A takes 100 points of damage for running into DDWL's 1600 defense with a 1500 ATK.
The question being is who gets the choice to remove first?
This one is quite simple, the turn player would have first choice on whether or not to remove. Player A would be the person to make the first choice on this, if they choose not remove, than it goes to Player B who has the choice now with their "
D. D. Warrior Lady". If they choose to remove than both monsters are removed from play. If not, than nothing happens and both monsters stay on the field, Player B's "
D. D. Warrior Lady" in face up defense position and Player A's "
D. D. Warrior Lady" in face up attack position.
Player A has a monster set in defense position.
Player B attacks Player A's monster with "
La Jinn the Mystical Genie of the Lamp".
Player A flips over their face-down monster to reveal "
Cyber Jar".
Damage Calculation is reached, with La Jinn destroying "
Cyber Jar".
The Resolve Effects step is reached and "
Cyber Jar's" flip effect resolves destroying all monsters on the field and causing both players to reveal their top 5 cards from their decks and special summon all level 4 or lower monsters in face-up attack mode or face-down defense mode.
Question is who has to play their monsters first in this situation?
Well, it is always the turn player who has priority"¦ so the same is no different here, the turn player must set their monsters first on the field before the opposing player. So in this example above, Player B would have to play their monsters on the field first due to the fact that it is their turn, and then Player A has the option to play their monsters on the field afterwards. Priority of this cannot be switched unfortunately.
Using Priority to activate other card effects:
The following was a highly debated theory and has now sense seemed to be proven to be true with recent UDE Judge List answers. I will refer you to this post made by Kevin Tewart here at
http://lists.upperdeck.com/read/messages?id=2416 on December 1, 2004.
Now to our own debated situation.
Incorrect:
Player A summons "
Giant Orc" and already has "
Catapult Turtle" face-up on the field.
Player B responds with "
Torrential Tribute".
Player A uses turn priority to activate "
Catapult Turtle's" effect to tribute "
Giant Orc" to "
Catapult Turtle" and deal 1100 points of damage to Player B.
Correct: Player A summons "
Giant Orc" and already has "
Catapult Turtle" face-up on the field.
Player B asks Player A "Are you going to tribute "˜
Giant Orc' to "˜
Catapult Turtle?"
Player A says, "Yes" and activates "
Catapult Turtle's" effect by offering "
Giant Orc".
Player B chains with "
Torrential Tribute".
Chain:
Link 1: "
Catapult Turtle's" effect is activated, sending "
Giant Orc" to the graveyard at this time as a cost of the effect.
Link 2: "
Torrential Tribute" is activated.
Resolution:
Link 2: "
Torrential Tribute" resolves destroying all monsters on the field.
Link 1: "
Catapult Turtle's" effect resolves dealing 1100 points of direct damage to Player B.
Reason: This was highly debated since no one could decide whether priority applied to the summoned monster that started the chain of events, or if any effect that was active in the chain events could be activated at that time. Now, does this mean that Player A could activate something like "
Pot of Greed" with turn priority? We don't know, but my guess is no based on the fact that to limit the use of priority only to the effects present on the field at that time during the chain of events makes more sense then to be able to activate any card in the game at that time. This was a touchy subject for so long and the fact that it was something that was ruled the exact opposite by UDE in the past at tournaments such as Worlds, and now it's being ruled the way that, in my opinion, it should have all along, since it makes the most sense and has the most backing of the game mechanic of priority with it caused a lot of controversy in it's own right.
But Kevin Tewart has assured the gaming community and all of Yu-Gi-Oh! that this is in fact the way that a situation like that would pan out, so who are we to complain now? We can't complain now.
This concludes my short, but informative article. I hope you learned something through this and have a better understanding of priority and what it is today. When the official UDE Priority Essay is revealed to the public, maybe we'll have more answers, but for now, I feel that my own article is the most accurate depiction of priority today. Thank you for reading and happy dueling!
