Forums Play Sword: Bulbasaur or Squirtle

Neither if your aim is to try different Pokemon. While Kanto starters are great(curious why you didn't do Charmander other than you already have a Fire Type) they're also heavily utilized. Only one I might consider is Venusaur from a Poison Type perspective but then there's Galarian Weezing with its good Ability.

No Zarichard? makes sad face for there is a lack of Zarichard
