Honor-Fight Theatre

Creature you control gain +1/+1
Activated abilities can't be activated during the
combat step if they would cause a creature to
become tapped.
At the start of each combat step untap all
creatures. Each player then separates their
creatures into 2 piles. Each player chooses one
pile they control and declare attacks with all
creature in that pile (even if it not their
combat step.) Each creature in the unchosen
piles must block if able.
