2* Mags definitely collects AP when Magnetic Flux goes off. “Reportedly” is pretty conservative language considering it does happen
Oh, and Quicksilver, Mr Fantastic, (and Coulson, who is missing anyways) can all collect AP using their swap powers. I’d say it’s at least as reliable as the random AP gains since you’re more in control of which color(s) you get, although you won’t always be able to make the match you want. Also Bag Man, for whatever that’s worth.
3 and 4 should do it as well, although admittedly much less. I don’t actually use him with anything other than 5 Red so I guess I haven’t personally tested the other ranks.
Update: For science! I tested this just now at rank 4, and I have confirmed that rank 4 does indeed also generate AP, although not nearly as much since it only destroys (at most) 9 tiles. Interestingly you do seem to get the 1 Red AP for the CD tile itself (mine was on an edge, destroyed 5 tiles plus the CD, no cascades, and generated 6 AP; 1 Red, 1 Blue, 1 Purple, 2 Black, and 1 TU).
I mainly used “reportedly” because that power’s description (like
) fails to specify whether destroyed tiles are collected. Hopefully those descriptions will get clarified at some point.
