Tactician's Standard

Creatures you control have banding.
(Any creatures with banding, and up to one without,
can attack in a band. Bands are blocked as a group.
If any creatures with banding you control are
blocking or being blocked by a creature, you divide
that creature's combat damage, not its controller,
among any of the creatures it's being blocked by or is
blocking.)
Bands with two or more creatures you control
have first strike.
