Hi all,
I am running a named themed team "avengers" and during my turn I use the hawkeye ID card to bring in adw chase hawkeye. Would I be able to have hawkeye use themed team probibility controls while he is still on my force?

If a player’s starting force is a named themed team, it can use TTPC. TTPC allows characters on that force to use Probability Control, up to X total times per game for that force. X is equal to the number of characters with the chosen keyword on that starting force, with a maximum of 5. In addition, a character using TTPC:
• Must have the chosen keyword.
• Must target a character other than itself.
• Must have 0 or 1 action tokens, and immediately is given an action token.

The reason for my question is what does the bolded "it" refer to: the player or the starting force?

As long as he meets the guidelines on your bullet points, he can use it. Nothing in the TTPC section says they have to be part of your starting force.
