When I play "Re-calibration Matrix" I always exclude scull rolls from the re-roll, as I assume that that the non-modification of sculls rule takes precedence.
a) Is that correct?
b) If the above is correct and re-calibration matrix is played in a roll where scarlet witch has rolled sculls, does that mean that sculls are not re-rolled but are still part of the final roll, thus contributing as "successes"?
