At the beginning of combat on your turn, up to one target creature you control becomes a copy of target creature an opponent controls.
Will of the council — Whenever chaos ensues, starting with you, each player votes for a creature you don’t control. Exile each creature with the most votes or tied for most votes.
If it becomes a copy of a token creature, it copies the original characteristics of that token as defined by the effect that created the token. It won't become a token creature.

The target creature you control copies the printed values of the other creature plus any copy effects that have been applied to it. It won't copy any other effects that have changed that creature's power, toughness, color, and so on. It also won't copy any counters on the creature, but it will retain any counters it already had on it.
