Alexios, Deimos of Kosmos

📖 How to build Alexios, Deimos of Kosmos

Alexios, Deimos of Kosmos is a four-mana, mono-red Human Berserker with trample. It attacks each combat if able, can't be sacrificed, and can't attack its owner. Its main engine is the upkeep trigger: at the beginning of each player's upkeep, that player gains control of Alexios, untaps it, puts a +1/+1 counter on it, and it gains haste until end of turn. The game plan is a hasty, growing attacker that changes hands around the table, so every player gets a bigger Alexios each turn.

Build around it with cards that remove blockers and push damage past them. Lightning Bolt and Abrade can clear small obstacles, while Chaos Warp and Blasphemous Act can handle larger ones. Professional Face-Breaker and Storm-Kiln Artist suit an aggressive red deck, and Faithless Looting or Big Score can help you keep finding action.

Watch out for a few things. Alexios must attack every combat, so it can be forced into bad blocks. Because control changes at each upkeep, you can't rely on keeping it, and the counters it accumulates go to whoever holds it, which may be an opponent. Its inability to be sacrificed also means sacrifice effects won't remove it, so you need other answers if it becomes a problem.
