Risky Research | Sorcery | | Surveil 2, then draw two cards. You lose 2 life. (To surveil 2, look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.) | Will Gist

Sandman's Quicksand | Sorcery | | Mayhem {3}{B} (You may cast this card from your graveyard for {3}{B} if you discarded it this turn. Timing rules still apply.) All creatures get -2/-2 until end of turn. If this spell's mayhem cost was paid, creatures your opponents control get -2/-2 until end of turn instead. | Mathias Kollros

Electro's Bolt | Sorcery | | Electro's Bolt deals 4 damage to target creature. Mayhem {1}{R} (You may cast this card from your graveyard for {1}{R} if you discarded it this turn. Timing rules still apply.) | Claudio Pozas

Kapow! | Sorcery | | Put a +1/+1 counter on target creature you control. It fights target creature an opponent controls. (Each deals damage equal to its power to the other.) | Arif Wijaya
