分枝演化

If a creature you control would enter the battlefield with a number of +1/+1 counters on it, it enters with twice that many instead.

If two or more effects attempt to modify how many counters would be put onto a creature you control, you choose the order to apply those effects, no matter who controls the sources of those effects.

If you control two Branching Evolutions, the number of +1/+1 counters put on a creature is four times the original number. Three Branching Evolutions multiplies the original number by eight, and so on.
