Everyone says that you can't Thunderbolt and get the FF ATA but that isn't entirely correct. If there is a FF team member using the FF ATA than an Avenger can be Thunderbolted to a WC which could in turn copy the FF ATA as long as the FF member using the FF ATA was around.

Read all of the thread and you'll see this was brought up and you'll see why your wrong.

The simple fact is you can NEVER use Thunderbolts to gain an Alternate TA granted by a feat. It is issue that the alternate TA does not exist until the game begins and you must declare Thunderbolts before the game begins. Hence Wildcards CAn copy Alt FF and other alt TA because they change TA every action.

It's even it's own question in the FAQ.

Ahhh, I see the problem. Go read Thunderbolts...the Avengers with Tbolts can not gain a wildcard team ability.

Perfectly stated clixer11. It states it right on the card that Thunderbolts cannot copy a Wildcard team ablility.

"After placing your team in your starting area, choose any one team ability other than a wildcard team ability or a team ability that cannot be copied by wild card team abilities. Members of this team gain the chosen team ability instead of the Avengers team ability, but their team affiliation does not change."
