Guardian Of Ascendancy

Flying, vigilance, lifelink
Ascend (If you control ten or more permanents, you
get the city's blessing for the rest of the game.)
Opponents can't ascend
Whenever another creature you control dies,
exile it and create a 1/1 spirit token with flying.

you control gain +3/+3 and lifelink.
