I'll help clarify the relationship between Mono-Red Burn and Prowess decks in the current tournament meta.
Based on tournament data, these are distinct archetypes in their respective formats:
In Pauper, "Mono Red Burn" is a dedicated archetype featuring Lightning Bolt, Galvanic Blast, and artifact-synergy creatures like Goblin Tomb Raider and Clockwork Percussionist. It has a 55% winrate over the last 30 days across 63 entries. However, "Prowess" refers to Modern's UR Prowess deck, which is completely different - it's blue-red, runs creatures like Dragon's Rage Channeler and Monastery Swiftspear, and relies on spell velocity rather than pure burn. Modern Prowess currently holds 8.57% of the Modern meta with a 49.28% winrate.
The confusion likely stems from the term "Prowess" being used for different strategies across formats. In Pauper, the closest aggressive red deck to what some might call "prowess-style" would actually be Red Madness, which is currently the top Pauper archetype at 10.97% presence. There is no "Monored Prowess" archetype tracked in tournament data - that term doesn't appear to be a standardized archetype name in either format.
