Ekko, Boy Savior

During your turn, Ekko has first strike. Predict - When Ekko attacks look at the top three cards of your library. Put one of them on top of your library and the others on bottom of your library in a random order. When you cast your fourth spell return each creature card from your graveyard that was put there this turn to the battlefield. They gain haste until end of the turn. This ability triggers only once each turn.
