My take on a Dominaria Remastered-style spin on Ravnica.

Azorius WU – Detain
Dimir UB – Transmute
Rakdos BR – Spectacle
Gruul RG – Riot
Selesnya GW – Convoke
Orzhov WB – Afterlife
Golgari BG – Dredge
Simic GU – Evolve
Izzet UR – Overload
Boros RW – Battalion

Defenders and Auras are subthemes in the cube.
