{3}{G}{U}: Until end of turn, Lush Outskirts becomes a 5/7 green and blue Plant creature with with ward {3} and “Whenever this creature attacks or blocks, torment yourself.” It's still a land. (To torment yourself, lose 3 life unless you discard a card or sacrifice a nonland permanent.)

Annihilation deals X damage to any target.

When Suitor of the Glade enters, put two +1/+1 counters on target creature you control. It gains vigilance until end of turn.
