Sha'dizh, Dimension Creator

Flying, Menace

You may cast spells from your graveyard with an additional {2} cost. Whenever you cast an instant or sorcery from your graveyard, create a 2/2 black Shade token with menace.
Whenever an opponent mills one or more cards, create a token that's a copy of a creature card in their graveyard, except it’s a black Shade with menace.

{2}{u}{b}: Return target instant or sorcery from your graveyard to your hand. You may cast it this turn. Exile it if you do.
