does anyone know if its legal to use hold the line with Rampaging Hulk's squash power?
Normally i think it would be clear but "Squash" isn't described as a power action.
anyone here have any suggestions?

Both Squash and HTL require their own non-free actions to activate. You may only give one of these to a figure per turn, so it would not work.

doh!.....thanks for the info....
