Pokémon Tournament

Middle-Evo Melee - A fight where only middle evolutions (or in the case of a 2-stage evolution, first evolutions) can compete in the battle. For example, instead of Blastoise, a player would use Wartortle, or instead of Houndoom, a player would use Houndour.

Pokémon which do not evolved are not allowed, including Ditto.

Any moveset is permitted, as long as it is a legal moveset for the Pokémon.

You cannot have more than 1 of the same Pokémon on your team, shiny or not.
