>>18648846I would take a look at Liquid Ooze Tentacruel. I know you can't talk about competitive Pokemon if you're sub-1800 ranking on Pokemon Showdown, but it's neutral to Grass, resists Poison, and using things like Leech Seed and Giga Drain only hurt it instead of healing itself. It also has access to Scald to burn it, and if you're dumb like me, it also has access to Hex, which was buffed to do 130 damage if the target has been statused. On top of that, it only takes shit from the Rotom-Wash part of the team core, as Heatran will not want to switch into a Water type, and Mega Saur's EQ.
