>>36527167I'm leaning towards Mega Meta if I'm gonna be honest. I think now that all the Megas are out and things changed so much since it got banned, I think it's worth a relook.
Running down the list
>Arceus formesAny problems the types may have are invalidated by their god tier movepools and stats.
>BlazikenCould be worth looking into except I think its ability to set up on a good amount of pokemon with SD+Speed boost and access to Z moves could put it over the edge too much
>Deo formesNot in a million years
>GenesectToo strong and unpredictable
>GroudonStupidly strong and bulky, SD or RP sets culd probably rip the tier in half
>SolgaleoPossible, but at the same time set up sets or even banded sets could be too much. Worth looking into
Honorary mentions that aren't on here but are worth mentioning
>AegislashNever. Terrains make this so much better and it enables absolutely AIDS 50/50s
>PheromosaLiterally only got better with tutors, pokemon like Marowak Alola can't switch in anymore and MAntine is irrelevant
