Mold Breaker is bugged. Mold Breaker is only supposed to ignore abilities that affect the mold breaker mon's moves (levitate, flash fire, sturdy, etc.), but on the calc, it cancels out all opposing abilities regardless of their effect. For example, calcing CB Azumarill's play rough vs. a haxorus yields this: 252+ Atk Choice Band Azumarill Play Rough vs. 36 HP / 0 Def Haxorus: 294-348 (97.3 - 115.2%) -- 81.3% chance to OHKO when it should be this: 252+ Atk Choice Band Huge Power Azumarill Play Rough vs. 36 HP / 0 Def Haxorus: 584-690 (193.3 - 228.4%) -- guaranteed OHKO The calc negated Azumarill's huge power because Haxorus has mold breaker, which is not how mold breaker works. Removing mold breaker yields the proper calc.
