So I was on r/stunfisk reading the post on allowing Reshiram in OU if it was available in gen 9 because chi-yu is supposedly superior to a mon that's always ubers. Context was relevant since I was doing some damage numbers on Reshiram, specifically against Ting-Lu, who has the ability Vessel of Ruin, which drops the special attack of all pokemon except itself by 25%. Now the interesting thing is on the calc, Turboblaze, is taken into account, which is basically Mold Breaker, an ability that ignores other abilities when doing damage. Now Mold Breaker/Turboblaze/Teravolt have always been specific to the abilities they ignore, mostly abilities that give you a type immunity or damage reduction (Levitate and Fluffy respectively). Bulbapedia has a list of these abilities that are ignored by Mold Breaker
here and Vessel of Ruin and Tablet of Ruin (Wo-Chien's ability which has the same issue I'm presenting here as the previously mentioned ability) are not on the list.
Now the new type immunity abilities like Well-Baked Body and Earth Eater are on the list, which makes sense to me but my question is, has Mold Breaker (the only available ignoring ability in gen 9) been tested to bypass the attack/special attack drop of Tablets of Ruin and Vessel of Ruin? If it has in-game, then no issue (Bulbapedia just needs to update their list but that would seem weird they would lack this information) but seeing how something like Dark Aura and Fairy Aura, somewhat similar abilities to the Ruin abilities, are no longer ignored by Mold Breaker, seems weird to be the case if they were ignored.
