Instant and sorcery spells you cast deal 1
additional damage.
Whenever a creature dealt damage by an instant
or sorcery you cast dies, look at the top three cards
of your library, choose an instant or sorcery from
among them, reveal it, and put that card into your hand, then put the rest on the bottom of your
library in any order.
Congratu-bloody-lations, you just called in the big guns.
