Bruna, the Tainted Light

Flying, Vigilance
When Bruna, the Tainted Light enters the battlefield, put two 2/2 white Gryff creature tokens with flying onto the battlefield.
At the beginning of your upkeep, if you control this creature and Gisela, the Goldnight's Wrath, exile them, then meld them together.
We are Bruna and Gisela...
