I stumbled across this combo when I was building an angels deck, and i made a list.
The Combo:
Bishop of Wings+Arcane Adaption+
Kaervek, the Spiteful (Or
Woe Strider)
Bishop of Wings has whenever an angel you control dies, create a 1/1 spirit, Arcane Adaption makes that a 1/1 flying spirit ANGEL, then you sacrifice it, and create another. You also gain 4 life every cycle of the combo. Kaervek gives it -1/-1 so you don't have to bother sacking it.
