Honestly, I would build off of that theme deck with an evolution line for infernape, with a couple victini ex to help build energy. Maybe something like this?
3-4 Infernape
1 Monferno
3-4 Chimchar
2-4 Victini EX
1 Victory Piece Ace Spec
4 Rare Candy
10-15 Fire Energy
Then of course whatever...
I came across my really old cards from the first generation, and I'm wondering what some of the popular decks were back in the day. If you know of any please link me to either a page that shows all the cards contained or list what you used back in the day if you had one.! :colorless:
