Wild Hex

Return up to one target permanent card from
your graveyard to your hand. Then target creature you control fights target creature
you don't control.

(as a hex resolves, an opponent of your choice shuffles it into their library face up instead of
you putting it into your graveyard. If this card would leave a library other than its owner's, its owner exiles it instead and may cast it for as
long as it remains exiled.)
