i think he just wanted to show how strong it could be if they hadn't limited it to the attack step, just look at other thing in the article:

But it says during each player's attack step that player's characters lose the affiliation. That implies that it only affects the player who has the attack step not that it affects all players during the attack step. So once the card activates it will affect both player's attack steps, but only one player has an attack step at a time. Thus the defender will always have their affiliations intact.

Can anyone else see comboing this with Mojo?

Actually, If you played this before a team attack fully resolved, would this void the attack and leave everyone involved exhausted?

Just making sure. I'm pretty sure it would work. This card seems more opt to wipe out your opponent's/s' offensive strategies than defensive tactics because of the obvious limiting text pointed out by nearly half the people on this board (this sentence referring the the MetaGame article).

EDIT: The article was edited.

As far as I understand it, if you were to play this card after the attackers in a team attack exhausted, it wouldn't stop the attack because once the attacker(s) exhaust, the attack cannot be stopped. The check for team affiliation happens at the time the characters exhaust. That is my understanding anyways.

The quote you mention is in reference to if the card wasn't limited to the attack step. Let's not put any more mistakes on the author than he may have actually made. :) Which currently totals in one. I'm hoping that this picture is just an older version of the card, myself. But either way, it's a definite must play card.
