4 rulings from Wizards of the Coast
- 1 October 2008A maximum of one nonbanding creature can join an attacking band no matter how many creatures with banding are in it.
- 1 October 2008If a creature with banding attacks, it can team up with any number of other attacking creatures with banding (and up to one nonbanding creature) and attack as a unit called a "band." The band can be blocked by any creature that could block a single creature in the band. Blocking any creature in a band blocks the entire band. If a creature with banding is blocked, the attacking player chooses how the blockers' damage is assigned.
- 1 October 2008Creatures in the same band must all attack the same player or planeswalker.
- 1 October 2009If a creature in combat has banding, its controller assigns damage for creatures blocking or blocked by it.
