Aezrebal, Sultan of Desire

Flying, trample, haste
Whenever Aezrebal deals combat damage to a player, each instant and sorcery card in your graveyard gains flashback until end of turn.
The flashback cost is equal to its mana cost.
If a card named Lamp of Leshrac is on the battlefield under your control, instant and sorcery spells you control have storm.
Partners with Lamp of Leshrac.
