Gisela, the Broken Blade (#24)

Type: Legendary Creature — Angel Horror

Text: Flying, first strike, lifelink
At the beginning of your end step, if you both own and control Gisela and a creature named Bruna, the Fading Light, exile them, then meld them into Brisela, Voice of Nightmares.

She now hears only Emrakul's murmurs.
