charizard y , venusaur, victreebel, blaziken/darmanitan , volcarona/talonflame, whimsicott
Lots of green pokemon are grass type , so use Whimsicott helping hand to charizard y/darmanitan/blaziken heat wave and win .
Venusaur is to deal with water/fairy type ( crawdaunt,gardevoir,...)
So something like :
Modest Charizard Y
Chlrophyll Venusaur Hp Fire
Scarf Darmanitian
Standard blaziken
Whimsicott with helping hand/encore/leech seed/stun spore or Sunny Day
Talonflame/volcarona
Although
Abamasnow + Snow Cloak Double Team Bright Powder Glaceon and Snow Cloak Bright Powder Beartic and Snow Cloak Brightpowder frolass are way more fun and fit the theme .
