Blessing of Vah Naboris

Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card whose converted mana cost is less than this spell's converted
mana cost. You may cast that card without paying its
mana cost. Then put all cards exiled this way that
weren't cast on the bottom of your library in a random
order.)
All red instant and sorcery spells deal an
additional 2 points of damage.
