Mannichi, the Fevered Dream

Gameplan

Mannichi is a toughness-matters aggro/combat deck: load the board with high-toughness, low-power creatures (often defenders or walls), then activate Mannichi to swap power and toughness and swing for huge unexpected damage. Turn to turn you ramp into beefy bodies, hold up the activation as a combat trick, and flip the switch at the perfect attack or block to blow opponents out.

Key Cards

• Wall of Earth — A 0/6 defender becomes a 6/0 attacker after the switch, a classic budget payoff.
• Doran, the Siege Tower — Color identity won't allow it, but high-toughness staples mirror its theme—use red equivalents instead.
• Brash Taunter — High-toughness body that survives the swap risk and pings opponents when damaged.
• Assault Formation — Lets your toughness-heavy creatures deal combat damage even without Mannichi as a backup engine.
• Hammerheim — Niche mono-red utility, but prioritize ramp and burn to keep activations flowing.
• Trove of Temptation — Forces attacks and ramps treasures, pressuring opponents while you set up swings.

Upgrade Path

Add efficient ramp (Treasure makers, mana rocks) so you can hold up the activation every turn while developing. Lean into damage doublers and trample enablers (Assault Formation, overrun-style effects) to make swapped attackers unblockable threats. Round out with mono-red card advantage like Wheel effects and impulse draw to fight through wipes and keep the gas flowing.
