Rennala, Full Moon Queen

Flying, Ward {3}

When Rennala enters the battlefield,
create three 1/1 blue Wizard creature tokens.

Sacrifice a token: Rennala is Indestructible
until end of turn.

At the beginning of your upkeep, return an instant or sorcery card from your graveyard to your hand. Then
if you control no tokens, sacrifice Rennala and return her
to the battlefield transformed under your control.
