How many times can you use a wildcard team ability in one turn? example can Dr. Doom use an aveneger free action move into stealth, and then use the Batman team ability on the same turn he used the aveneger team ability????

From the Universe PAC:
Minions of Doom
Members of this team act as wild cards. They can use any team ability that any friendly fi gure on the battle map possesses. They may use this ability once each action.

This is the text from Minions of Doom, but all wildcard TAs have the dame wording. As you can see, the wildcards can switch TAs every action, so you can use multiple TAs a turn. Dr. Doom can use the Avengers TA and then Batman TA. He can even do more, depending of the situations of any given turn and the number of available TAs on his team.
