{u}{u},{t}: Draw cards from your library until you
find a Persona card and put it into your hand.
Return the other cards to the top of your library
and shuffle your deck afterwards.

permanents to play a Persona card from your
hand without paying mana costs. The sum of the
power of the sacrificed Personas must be greater

of the summoned Persona.
