I think I'll be voting no ban for Murkrow, because it's not inherently broken. I used mostly stall and semistall teams to get reqs, and there are plenty of stallbreakers that don't rely on stat boosts (such as Kecleon-Azelf, Mawile-Tapu Koko, and other more niche breakers like Octillery-Heatran and Sun-boosted Victini inheritors). Additionally, I don't believe that the banning of Murkrow will impact stall as people think, because common Mold Breaker abusers such as Haxorus-Garchomp and Rampardos-Terrakion are walled by Celesteela and Buzzwole, respectively, which do not require Prankster to check setup. A better way to allow more playstyles to function effectively is to allow mons to inherit from Megas and Ubers (as I've mentioned before), which gives BO and offense more sets to break stall, such as Drizzle + Water Spout, Teravolt + Hone Claws, and Fairy/Dark Aura.
Additionally, I'd like to add some noms.
Marowak (Kecleon) UR -> B+ or A-
The Kanto version has a good niche over Alola in its resistance to Stealth Rock and immunity to Electric, though Alola has more resistances.
Toxapex B -> B+, move Emolga to first
Toxapex is amazing at checking mixed attackers like Kecleon-Azelf, Victini inheritors, and Tapu Koko, though it is pretty passive with a lackluster attacking movepool.
Chandelure B- -> A-
Salazzle B -> A-
I have no idea why these are so low. Drought Choice Specs Eruptions hit like trucks and also help setup for Victini inheritors to smash through opposing stall, while Scarf is a nice special revenge killer on Chandelure that doesn't lose to Alolan Muk (although it needs full health).
Tyranitar-Mega C -> C+ or B-, add Mew
With Drought abusers on the rise, Tyranitar-Mega is a really nice special wall that beats them both reliably. Mew gives it Knock Off, Will-o-Wisp, and U-Turn.
Doublade C+ -> B- or B, move Swoobat up
Doublade checks things like Terrakion, Tapu Koko, and Archeops super nicely, which otherwise threaten stall teams. Its weakness to Knock Off and competition with Sableye-Mega hurts it, though.
Cobalion (Hawlucha) UR -> B-
Cobalion @ Fightinium Z
Ability: Mold Breaker
EVs: 252 Atk / 4 Def / 252 Spe
- High Jump Kick
- Iron Head
- Swords Dance
I faced this a few times during my reqs laddering, and goddamn is it annoying. Doesn't care about Masquerain Buzzwole at all, doesn't care about Toxic, doesn't care about Knock Off, really nice offensive typing. Give it cleric support and it gives stall hell.
