Dolita, Vegetation Queen

As a creature enters or leaves the battlefield, if that creature is under an opponent's control, you may pick one:
•Target creature gets -X/-X until end of turn where X is that creature's toughness.
•Exile a creature you don't control and it enters the battlefield tapped at the end of the turn with a -1/-1 counter on it.
•Look at an opponent's hand and chose a card from their hand
