πŸ“– How to build Koma, World-Eater

Koma, World-Eater is a seven-mana Simic creature that can't be countered and has trample and ward {4}. Whenever it deals combat damage to a player, it creates four 3/3 blue Serpent tokens named Koma's Coil. The game plan is to get Koma onto the battlefield reliably, attack through the defenses, and turn each connecting hit into a large board of Serpents.

Build around ramp so Koma arrives on time. Cultivate, Farseek, Nature's Lore, Rampant Growth, Kodama's Reach, Birds of Paradise, and Three Visits can all help reach seven mana sooner. Rhystic Study adds card advantage to keep pressure up. Heroic Intervention can help protect Koma's board, Counterspell can answer opposing spells, and Beast Within can remove a blocker that stands in the way of the attack.

Watch the cost and the single-threat nature of the plan. Koma needs seven mana, so it can be slow without ramp. Ward {4} makes targeted removal expensive for opponents, but it doesn't stop them from paying. Koma only triggers on combat damage to a player, so a well-placed blocker can stop the attack. Trample helps only when damage exceeds the blocker's toughness, and the four tokens depend entirely on Koma connecting.
