If 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. |

A maximum of one nonbanding creature can join an attacking band no matter how many creatures with banding are in it. |

Creatures in the same band must all attack the same player or planeswalker. |

Paying cumulative upkeep is always optional. If it's not paid, the permanent with cumulative upkeep is sacrificed. Partial payments of the total cumulative upkeep cost can't be made. For example, if a permanent with "cumulative upkeep  " has three age counters on it when its cumulative upkeep ability triggers, it gets another age counter and then its controller chooses to either pay  or sacrifice the permanent. |

If a creature in combat has banding, its controller assigns damage for creatures blocking or blocked by it. |
