I agree with all the discussion in here and the conclusions reached, and would also say that Taskmaster could not acquire probability control off of the opponent's Reality Gem use.

Ah, OK: so the issue is when Taskmaster looks for a power to copy the Gauntlet figure isn't a charadter who can use PC so it can't be copied. That makes sense.

Yes, the standard powers chosen for special powers 2 and 3 can be picked by Taskmaster. They can use a standard power, that power is fair game for Taskmaster.
