Eject Button Amoonguss Grass
Back for my second attempt at making a Grass team. This team is largely based off the CCAT that Asruna~Keaton and I co-hosted, which was around Ogerpon-Hearthflame.

Brambleghast is our resident entry hazard remover. Spell Tag and max Attack EVs actually let it OHKO Flutter Mane 56.3% of the time, while boosting Poltergeist to be a fairly threatening move against Ghost-types like Gholdengo and Skeledirge. Rapid Spin and Spikes allow this thing to set and remove hazards, although Strength Sap can be run over Spikes if the recovery is needed. It's a rather under-rated option due to its ability to threaten spinblockers and remove hazards efficiently.

Abomasnow is the catalyst for our setup sweepers. 8 turns of Aurora Veil mean that your sweepers become incredibly threatening, letting them set up far easier. It also functions as our main special attacker, with Blizzard nailing Flying-types, and Ice neutrality (although boosting the opponent's Defense isn't what you want). Pretty self-explanatory addition to the team.

Ogerpon-Hearthflame, the 'mon the CCAT was built around. Swords Dance + Horn Leech under Veil can easily become incredibly hard to defeat, while Ivy Cudgel smacks Steel- and Ice-types. Its Ice neutrality is also appreciated, giving the team a chance against the type (although don't be praying - it's still an insanely hard matchup) Finally, it harasses Fairy teams thanks to its resistance.

Scarf Meowscarada has been a staple on Grass before the DLC (and HOME), and it remains as our speed control option on this team. Not much else to say.

Shell Smash Torterra blessed Grass during the DLC. Headlong Rush and Rock Blast, in tandem with Loaded Dice, allow this 'mon to easily sweep under Aurora Veil. Loaded Dice Bullet Seed is also incredibly powerful. This is the 'mon of choice in the Fire matchup, while also helping significantly alongside Ogerpon-Hearthflame in the Poison and Steel matchups. It also puts in lots of against slower teamstyles, like bulky Water and stall Poison.

During the CCAT, the Monotype room discussed the inability of Grass to bring its sweepers in safely without sacrificing a crucial part of the team. Eject Button Amoonguss, a solution proposed by some of the higher-ups and used on this team, found its way here as a blanket switch-in that also lets you either set up Aurora Veil or setup and sweep with either Ogerpon-Hearthflame or Torterra. Additionally, the damage it takes on that switch-in is mitigated by Regenerator. Beyond that switch-in, though, Amoonguss puts in work to bring our sweepers in. Spore can either create a setup opportunity or temporarily immobilize a key switchin to the aforementioned threats. Not only that, but it helps immensely in the Fairy matchup alongside Ogerpon-Hearthflame. Not to mention, Regenerator plus pretty decent stats lets it be a good wall. Overall, Eject Button Amoonguss is the glue that holds the team together.
