Grave Researcher

At the beginning of your upkeep, surveil 1. Then if there are three or more creature cards in your graveyard, this creature becomes prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.)

Al comienzo de tu mantenimiento, escruta 1. Luego, si hay tres o más cartas de criatura en tu cementerio, esta criatura se prepara. (Mientras esta criatura esté preparada, puedes lanzar una copia de su hechizo. Si lo haces, deja de estarlo.)

Reanimate

Put target creature card from a graveyard onto the battlefield under your control. You lose life equal to that card's mana value.
