Banshee Crown

Equipped creature has vigilance and "Whenever a creature with flying you control deals combat damage, put a 2/2 blue Spirit creature token with flying onto the battlefield."
At the beginning of your upkeep, if you both own and control Banshee Crown and a creature named Avlyen, Giest Mage, exile them, then meld them into Avlyen, Specter Queen.
