Legendary Artifact
At the beginning of your end step, exile up to one target legendary creature card from a graveyard with a memory counter on it.

: Until your next turn, target legendary creature you control becomes a copy of target creature card in exile with a memory counter on it. Activate only as a sorcery.
If either one of the targets of The Animus’s last ability is illegal when the ability begins to resolve, nothing will happen when the ability resolves.
