Pokémon Expedition has many double and triple battles as well as a handful of 3v2, 2v3, 1v2, etc. Features the Rocket Clone Type arc inspired by the First Movie and has an update coming in the next week to allow for ability inheritance via breeding. Vast egg pools for all Pokémon. Want a Charizard with Poison, Water and Grass type moves and the ability Static? Love Butterfree, but not how it's not much use after the second badge? All Pokémon are viable, so feel free to build whatever team you want and not have to struggle. My life partner beat the game with a Butterfree on her team and she's a complete Pokémon noob. Nuzlocke mode coming in the next update as well if you're into that.
