There might not be enough before the first gym, since all I've seen is mudkip as a starter, and marshtomp's stab ground moves become part poison on Venam's field. If that's not a problem somehow then idk.

I currently have no idea of the availability of each type on early game, definetively it's going to be something to work on before trying... thanks!

Edit: Ah, I looked around and it looks like the Nidorans are also available (which fits bc Nidoking/queen are ground types) and Geodude, I think?

I can't believe I didn't think of Nidoran, since he's right there on the pier. That actually looks like a solid start to the run, with magnitude for Venam and two Poison types for Keta. Good luck on your run!
