Magecraft—Whenever you cast or copy an instant
or sorcery spell, you may have target artifact creature
you control deal damage equal to its power to target creature you don't control. If a creature died this
way, you may draw a card, if you do discard a card.

Tap X untapped artifacts you control: Target instant
or sorcery card in your graveyard costs X less to
cast.
