Trisha, Forgotten Mother

Indestructible
At the beginning of each player's turn, if Trisha, Forgotten Mother is in your commander zone,
search your library for a creature card with
converted mana cost 3 or less, reveal it, put it in
your hand and shuffle your library, then Trisha
deals damage equal to the revealed card's power
to any target.
Whenever Trisha enters the battlefield, return
target creature to its owner's hand, then that
player discards a card.
