Clamavus enters the battlefield and immediately grants all your creatures +1/+1 for each creature type they share with the creature you just cast — a static anthem that stacks fast in tribal and typal lists. The Swarmlord decks run it in over 70% of builds because a single Tyranid trigger can push the entire board into lethal range before opponents react.

Commanders with the highest synergy
The Swarmlord
The Swarmlord's Tyranid army shares creature types across nearly every card in the deck, so Clamavus turns each new cast into a board-wide pump that compounds as the swarm grows.
Magus Lucea Kane
Magus Lucea Kane copies spells and creatures with abandon, and Clamavus rewards that density — every copied Tyranid or mutant that hits the battlefield means another layer of +1/+1 across a board that already wants to go wide and tall simultaneously.
Sovereign Okinec Ahau
Sovereign Okinec Ahau cares about creatures with high power attacking, and Clamavus reliably pushes the whole team over whatever threshold Ahau's ability is tracking, converting modest boards into lethal attacks.
Minsc & Boo, Timeless Heroes
Minsc & Boo, Timeless Heroes leans on Hamster and Ranger synergies that naturally cluster creature types, so Clamavus provides a consistent anthem that makes Boo's pump ability even more punishing when combat math gets out of hand.

Commander is where Clamavus lives — tribal decks in a 100-card singleton format are exactly the shell that maximizes the anthem's stacking potential, and the card sees heavy play there. Legacy and Vintage legality is technically on the books, but tribal strategies in those formats demand much faster engines and Clamavus at three mana is too slow to compete with the broken things those formats are doing. Oathbreaker offers another Commander-adjacent home where a tribal gameplan can realistically develop, and Clamavus is a reasonable include there too.
