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 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.

In a two-player game, you exchange control of two permanents of your choice with your opponent.

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

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.

The control-change effect of Inniaz’s last ability lasts indefinitely. It doesn’t wear off during the cleanup step, and it doesn’t expire if Inniaz leaves the battlefield. In a multiplayer game, a player who leaves the game takes back their permanent and gives back the one they took.
