I believe this is the first challenge for a spinoff game, so without further ado...
Rules
All cards are allowed to be used, except the 4 legendary cards.
The challenge ends after you beat Ronald at the Pokemon Dome.
You may use an emulator, but Gameshark Codes are not allowed, except to get the Venusaur and Mew Card Pop Cards.
You cannot use any deck made from Dr. Mason's auto-deck machines.
The Challenge Hall tournaments are optional. You do not have to participate in it if you don't want to.
This challenge is only for the first TCG game. Please refrain from using TGC2.
You can choose any type from the seven listed below, regardless of whether another user is using the same type or not.
Types
Here are the 7 TCG Types to choose from, as well as the main series types each comprises.
Colorless (Normal, Flying, Dragon)
Fighting (Fighting, Rock, Ground)
Fire (Fire)
Grass (Grass, Bug, Poison*)
Lightning (Electric)
Psychic (Psychic, Ghost, Poison*)

*Poison was switched from Grass to Psychic starting with the D\P expansion. Therefore, I will allow Poison-type Pokemon to be used if you choose Psychic.
