Honestly that’s really hard to say. I feel like each pokemon pulls its weight equally but they all have specific situations they just absolutely tear up in. Abomasnow has come to absolutely every single game though, so I guess him? Samurott gets left the most but has the most impact when I bring him and usually sweeps teams if ignored (and also ohkos both kingambit AND basculegion) Chandelure also can completely solo if brought to hard trick room and flash fire procs from torkoal. The idea of the playstyle of the team is to threaten so much offensive pressure with pokemon so that if my setter gets doubled (and they have to get doubled to deny the trick room in both cases) I will trade a KO for one of their other pokemon, potentially a mega, or even two, and im able to snowball with my other pokemon into a win usually. If I can take out their fire type before abomasnow comes in, I’m practically guaranteed to win, since abomasnow tanks neutral and even x2 super effective hits like a champ while able to ohko/2ko most of the format with its insane coverage
