Alexios, Deimos of Kosmos puts immediate pressure on the table by forcing opponents to attack each other or hand you value, and the punishment clause makes ignoring him costly. The catch is the mana investment and the fact that he telegraphs your intentions clearly — Zidane, Tantalus Thief decks absorb that cost better than most because they're already engineering combat chaos.

Commanders with the highest synergy
Zidane, Tantalus Thief
Zidane, Tantalus Thief runs Alexios, Deimos of Kosmos in over 70% of lists because both cards are pushing the same lever — forcing opponents into attacks that Zidane can exploit for stolen goods and extra value.
Kratos, God of War
Kratos, God of War wants bodies in combat and opponents swinging at each other, and Alexios, Deimos of Kosmos delivers both conditions reliably while Kratos capitalizes on the resulting damage and deaths.
Xantcha, Sleeper Agent
Xantcha, Sleeper Agent builds around gifting threats and manipulating opponent decisions, and Alexios, Deimos of Kosmos slots in as another political pressure piece that punishes anyone who refuses to play along.
Iroh, Tea Master
Iroh, Tea Master rewards opponents for attacking each other and generates value from chaotic combat, making Alexios, Deimos of Kosmos a natural complement that keeps the table moving in the right direction.
Karazikar, the Eye Tyrant
Karazikar, the Eye Tyrant goad effects and Alexios, Deimos of Kosmos stack cleanly — opponents who are already goaded and feel the Alexios pressure have very few clean answers, creating a gridlock that benefits the controller.

Commander is where Alexios, Deimos of Kosmos actually does something — three or more opponents means his forced-attack and punishment effects hit a real political matrix, and the chaos he generates scales with table size. In Legacy and Vintage he's technically legal but competing against the most efficient threats and interaction in the game, and a four-mana do-nothing-immediately creature doesn't survive long enough to matter in those formats. Oathbreaker offers a middle ground where the 20-life total makes his pressure more relevant, though the smaller deck size and faster games mean he needs to come down early to have impact.
