Zan, the Blank Canvas

Whenever you draw a card, you may pay {2} and
reveal a creature card from your hand. If you do,
Zan becomes a copy of that creature until end of
turn, except they have this ability.
{4}: Choose target creature you don't control.
You and that creature's controller each draw a
card, then you may have Zan gain all abilities of
that creature until the end of your next turn.
