I'm a somewhat new player just started last month so the whole game is relatively new. My question is about the T-bolts feat card, can I give my Avengers ANY team ability or do I have to copy from a character on my force wildcard style, any judges please respond. Thanks

Any copyable TA in the game is available to Avengers using Thunderbolts. They don't need, for example, a Skrull Warrior on the team to copy the Skrull TA.
