Theros Beyond Death

Protean Thaumaturge | Creature | Human Wizard | Constellation — Whenever an enchantment enters the battlefield under your control, you may have Protean Thaumaturge become a copy of another target creature, except it has this ability. | Izzy

Thassa's Intervention | Instant | | Choose one — • Look at the top X cards of your library. Put up to two of them into your hand and the rest on the bottom of your library in a random order. • Counter target spell unless its controller pays twice {X}. | Zack Stella

Thassa's Oracle | Creature | Merfolk Wizard | When Thassa's Oracle enters the battlefield, look at the top X cards of your library, where X is your devotion to blue. Put up to one of them on top of your library and the rest on the bottom of your library in a random order. If X is greater than or equal to the number of cards in your library, you win the game. (Each {U} in the mana costs of permanents you control counts toward your devotion to blue.) | Jesper Ejsing
