Inniaz, the Gale Force

In a Two-Headed Giant game, Inniaz’s ability ignores who’s on which team. The leftmost player on each team gains control of a teammate’s permanent, and the rightmost player gains one from the opposing team’s leftmost player. If your teammate gains control of an attacking creature this way, it’s still removed from combat.

Inniaz’s ability resolves even if some or all of the attacking creatures lose flying or leave combat before it resolves.

You choose the permanents to be blown over to other players while Inniaz’s ability is resolving. No player may take actions between the time you make the choices and the time control changes.

If any player controls no nonland permanents, the player to their left doesn’t gain control of anything.

If you give away a creature you control with flying that attacked, it’s removed from combat. It will still be tapped if it was tapped, so it won’t be able to block.
