Ysbryd

Whenever Ysbryd attacks, you may destroy
target artifact or enchantment.
Artifact and enchantment cards in each
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?"
