see your taking into considering there wont be a spell speed 3 flying around.
not to mention you would have to have 4 spell or traps that have to be able to chain to each other. in order to make
Emergency Provisions effective, not to mention itll only be YOU activating quickplays from your hand not your opponent.
not to mention cards that miss their timing wont help out at all. see there is a limitation you just have to count.
lets make a sitution were its you going first, i only have 5 spell speed 2 type cards, spell and traps included. and you have lets say, 5 card hand, all 5 can chain to each other, which means they are all quickplays.
you have 1 normal, and 3 other chainable effects. per for example lets say its
Heavy Storm, and you want to create a really insane chain.
so first you play
Heavy Storm.
YOU Link 1:
Heavy Storm
ME Link 2:
Waboku
YOU Link 3:
Book of Moon Targeting a face up monster
ME Link 4: HOrus 8 to negate it
You LInk 5:
Scapegoat
Me Link 6: HOrus 8 to negate it
You Link 7:
Rush Recklessly
Me LInk 8: Horus 8 to negate it
You Link 9:
Emergency Provisions (From hand, to make room for the remaining 4 spells in hand)
Me LInk 10: Horus 8 to negate it
now we will stop here, because any smart person will know that chaining the remaining quickplays will lead to you wasting your hand and me negating, but oviously it would go to 14, with me only wasting 1 card. heck i didnt even have to waste that
Waboku, and easily drop the Chain number to 13. but easily, notice that the number wont ever go that high if there is a quick easy negator on the field.
you wont ever get to a quick 20.
by the time you get to 20 you will oviously have to have a deck packed full of effects that are just speed 2 and nobody chains with a speed 3.
but we all know that its impossible becuase then you would have to be playing with your deck, which then would have to consist of using
Emergency Provisions 3 times. which at the current moment you cannot.
but just for the sake to see how big a chain in yugi can get, we can say we use 3 provisions.
not to mention, that you cannot interupt the chain, unlike in VS or Magic.
once one card resolves you can chain to that and so forth.
