Shaun, Archenemy

Whenever one or more creatures attacks you,
you may draw a card. If you do, discard a card
or lose 2 life.
{x}{u}{b}: Exile target nonland card in a graveyard
with mana value X or less. Copy that spell. You
may cast the copy without paying its mana cost.
A token created this way is an artifact in addition
to its other types.
