War of the Spark

Ravnica at War | Sorcery | | Exile all multicolored permanents. | Adam Paquette

Solar Blaze | Sorcery | | Each creature deals damage to itself equal to its power. | Adam Paquette

Widespread Brutality | Sorcery | | Amass 2, then the Army you amassed deals damage equal to its power to each non-Army creature. (To amass 2, put two +1/+1 counters on an Army you control. If you don't control one, create a 0/0 black Zombie Army creature token first.) | Victor Adame Minguez
