I say allow Encore and Heal Bell.
Encore is honestly a non-issue for Mollux as, though it enables CAP to capitalize on an opponent's mistake and punish a switch in, CAP's lack of a boosting move means it has little to do besides burn or deal some decent (likely not fatal if the opponent switched to a counter) damage to the switch-in.
Heal Bell does little for CAP itself as Mollux is immune to 2 of the 4 most common status moves; however, it does further its role as a supporting pivot by allowing it to help its team out further. Heal Bell can only help Mollux find its way onto OU teams. Along with Recover, it can actually give CAP3 a niche in OU of an outstanding wall/cleric that can actually attack.
