People missing Mega Evos is the turn I didn’t expect to see but then again Dyna/Gigantamax are just reductive versions of it anyways. I dislike both for their own reasons (Some Megas should’ve been actual evolutions and Dynamax forms are just a retread of Mega Evoultion). The remake of the Sinnoh games having Dynamax gimmick makes sense since ORAS introduced Mega Evos to the Hoenn storyline. Koffing still has “Levitate” in Gen 8 (or else it would’ve been replaced like with what happened to Gengar’s ability in Gen 7). You just need to catch/breed one to get the opposite main ability or use the ability capsule.
