Trying to make a new poison deck tell me what you think

To be honest, I'm not sure how many games you're going to win with this. It's okay, but mostly just saved by it's dark typing, which Gardevoir ex and Mew VMAX are weak to. what is the absol doing in there? I would replace the Mux with a Paldean Clodsire ex line and maybe add some more stadiums. Definitely add more Dark Patch, that is the entire energy acceleration engine. But after those upgrades it's looking a lot better. Maybe some trekking shoes for additional consistency and another way to discard dark energies. You might want to remove the Roxanne, Iono is better in almost every game.
