How hard is it to believe that some effects do a "Self-Sustainment" to check for their ability to remain active on the field?
Its not always on all equip cards that they should be destroyed when the monster they are equipped to is removed from the field, but we know that it no longer has a reason to remain active.
Continuous Effects that have the "infinity" symbol, must have it for a reason other than, "It remains on the field past its activation".
What causes that? Is it explicitly the symbol, or the effect combined?
Nightmare Wheel states that when the selected (yes its past tense, only because once it's selected, do you have to keep selecting it each turn???) monster is removed from the field, meaning "face-down" doesnt qualify,
Nightmare Wheel is destroyed.
Again, how does it know to destroy itself unless it continually checks the status of the selected card.
Q: Hmmm, is the card I am inflicting damage from still on the field... Let me check.
A1: It's face-down, but still there.
A2: It was tributed. I guess my job is over.
It's clearly not the player that does the check, although we know in reality, can a card do it by themselves? The "Conditional Effect" states that in order to remain active, there must be a card
selected continually, without break.
How can that not be a Continuous Targeting Effect?
