Ascend (If you control ten or more permanents, you get the city's blessing for the rest of the game.)

Return target nonland permanent to its owner's hand. If you have the city's blessing, you may put that permanent on top of its owner's library instead.

Kicker (You may pay an additional as you cast this spell.)

Choose target creature with mana value 3 or less. If this spell was kicked, instead choose target creature. Exile the chosen creature, then its controller gains life equal to its mana value.
