Merel, The Lady of the Forest

Landfall — Whenever a land enters the battlefield under your control, put a life counter on target Bird, Mouse, Rabbit, Raccoon or Squirrel, or draw a card.

At the beginning of your upkeep, you may
look at the top card of your library. If it's a land,
you may place it onto the battlefield. If it's a creature, you may place it at the bottom of your library.
