Lifelink, Trample

Daybound
(If it’s neither day nor night, it becomes day as Beruth, the Thirsty enters the battlefield. Track day and night for the rest of the game.)

Whenever Beruth, the Thirsty deals combat damage to a player, put a +1/+1 counter on it. If it's night, put two +1/+1 counters on it instead.
