Ysbryd

Whenever Ysbryd attacks, you may destroy target artifact or enchantment.

Artifact and enchantment cards in opponent's
graveyards have "Exile this card from your
graveyard, it deals damage to Ysbryd equal to its
mana value."

"Plenty of good slag and pot metal in their scat, but
it's all jinxed up. Who knows what spell residue will
blast out if you start hammering it?"
