Reach, Deathtouch
Hellbent—Exile a nonland card from your
graveyard: Copy that card, until end of turn you
may cast the copy. If a spell cast this way would
become a creature token, it's colorless and is an artifact golem, in addition to its other types.
Activate only if you have no cards in hand.
{3}{t}: Each player discards a card.
