Patia, Bound by Fate

Whenever one or more creatures attack one or
more of your opponents, flip a coin. If you win
the flip, each creature attacking one or more of
your opponents gets +X/+0, where X is that
creature's power. If you lose the flip, each
creature defending players control get +X/+0,
where X is that creature's power.
Whenever you win a coin flip, scry 1.
