Prowess Cube is a 5 color prowess and prowess-adjacent themed cube. The cube is designed to have a prowess game-plan of mostly spells with 7-10 creatures to aggressively push damage in.
Supported themes include:
Fixing in the cube is mostly done with fetch shock manabases, to create a relevent risk-reward for playing 3+ color decks. The land counts favor red, as red will be the most plentiful color.
The cube is on 405 cards to have a small amount of randomness between drafts but also to have enough cards to facilitate a 9th player if issues ever arise with too many attendees.
