Active Team

In the Two-Headed Giant variant, the active team is the team whose turn it is. The active team gets priority at the start of each phase or step (except for the untap and cleanup steps), after any spell or ability (except a mana ability) resolves, and after combat damage resolves. See rule 200.3 and rule 606.6c.
