Legion Reconsecrator (YLCI-011) - Alchemy: Ixalan

Whenever Legion Reconsecrator attacks, exile up to one target creature card from a graveyard. If you do, conjure a duplicate of it into your graveyard. The duplicate perpetually becomes a black Skeleton with base power and toughness 3/1 in addition to its other colors and types.
When Legion Reconsecrator dies, return another target creature card with power or toughness 1 from your graveyard to the battlefield.
