Spellstitched Skaab

As an additional cost to cast Spellstitched Skaab,
exile a creature card from your graveyard and an instant card that could target it from your hand.
Flying, menace
When Spellstitched Skaab dies, you may exile it.
If you do, put the exiled creature card onto the battlefield. Then, cast the exiled instant card
without paying its mana cost. You must choose
that creature as one of its targets if able.
