Pokémon Violet - Unrivaled Hisuian Decidueye 7-Star Crystal Raid Solo

The Hisuian Decidueye raid battle has landed, and it seems to be pretty easy to solo compared to the Mewtwo raid battle. For this battle, I used an Eternatus with 252 EVs in Special Attack and Defense, Modest Nature, holding a Shell Bell. Its moveset is Cosmic Power, Recover, Venoshock, and Sludge Bomb.
The strategy is to fire off a Sludge Bomb on turn 1 since Cosmic Power is pointless here. After Decidueye resets your stats, then you can spam Cosmic Power until you are at +4 Defense. You should use Recover whenever you are low on health, then start spamming Sludge Bomb hoping for another poison. Once poisoned, a Tera boosted Venoshock should deal a ton of damage, allowing you to heal with Shell Bell. Keep on using that move until you defeat it.

Finally a raid where a box legend can be useful

wonder how this could go with teammates

Should be much easier as long as everyone has the same build. Since Sludge Bomb has a 30% chance to poison the opponent, with four people, it is more likely to happen after the shield is up, then everyone can just spam Venoshock.
