Shadecaller

At the beginning of your end step, you may exile target creature card from a graveyard. If you do,
create a token that's a copy of that creature,
except it's black, it's 1/1, and it's a Shade in
addition to its other types. At the beginning of
your next turn's end step, exile that token.
