Jaedenkaal said: He only steals AP from one AP pool, so the only way he's guaranteed to steal 8 is if the enemy team has at least 8 AP in every color. I believe he can also steal Team-Up AP in this way. Basically his power picks a random enemy AP pool with at least 1 AP in it, and steals up to 8 of that AP.

Dayv said: Here's a neat idea on a way to both fix and improve this skill:"Steals up to X enemy special tiles. If there are less than X enemy special tiles, steals 2 AP from a random enemy AP pool for each tile not stolen."So if you have it at five covers (where X = 4), and the enemy has only two special tiles, you steal those two tiles and 2 AP each from two randomly selected AP pools.(You could leave 3* Star-Lord as is, though, with the text-only fix. 5* SL needs better differentiation from 3*.)
