Mono-Red Prowess is aggressive and low-cost, so cheap efficient interaction is at a premium. Ray of Enfeeblement is a cheap instant-speed trick that cripples Monastery Swiftspear, Soul-Scar Mage, Emberheart Challenger, and Screaming Nemesis in combat by shrinking their power by 4. It won't kill any of them on its own, so use it to blank an attacker's damage or to finish a creature that has already taken damage. Unlicensed Hearse can grow into a real threat by exiling the burn spells and dead creatures that pile up in graveyards, though it needs a crew and starts out tiny. Graveyard Trespasser is too narrow against this curve-out plan, and Sentinel of the Nameless City's 4-toughness body survives an unkicked Burst Lightning but still falls to Reckless Rage and kicked Burst Lightning, so both come out for faster interaction. Culling Ritual stays in the deck, since it wipes out Swiftspear, Soul-Scar Mage, Emberheart Challenger, and Kumano Faces Kakkazan.
