"B", Arcane Manipulator

Whenever "B", Arcane Manipulator deals
combat damage to a player, you may draw a card.
If you do, discard a card.

{u}{b}{r}{t}: Exile target instant or sorcery card from
a graveyard. You may cast that card without paying
its mana cost. If a spell cast this way would be put
into a graveyard, exile it instead.

to be wielded."
