Battalion

Battalion is an ability word introduced in Gatecrash, wherein it is the Boros Legion guild mechanic. It gives an advantageous effect when a creature with battalion attacks alongside 2 or more other creatures. The mechanic was designed or inspired by Shawn Main, who, for the Great Designer Search 2, submitted "Assault". Dragon's Maze added 2 cards with batallion.

Rulings

 * The three attacking creatures don't have to be attacking the same player or planeswalker.
 * Once a battalion ability has triggered, it doesn't matter how many creatures are still attacking when that ability resolves.
 * The effects of battalion abilities vary from card to card. Read each card carefully.

Trivia

 * Haazda Marshal and Makeshift Battalion both have unlisted Battalion; the cards are a callback, as both are from sets from Ravnica. Kytheon, Hero of Akros also has unlisted Battalion, though the connection is more tenuous, with Akros being a -flavored city.
 * Odric, Master Tactician has a more demanding version of Battalion that casts a much more powerful spell (Master Warcraft, also a Boros card).
 * On silver bordered cards, one variant of Garbage Elemental has Battalion.
