My recommendation to lead the deck is
The fact that a mid-2000s Gold Star, a 2002 Shining card, and a 2000 Gym Challenge holo all sit in the top 10 alongside modern SIRs and the legendary Base Set variants speaks to the unique position that Charizard occupies in the market: there is no era of the game where Charizard is not relevant, and there is no era where the best Charizard card is not among the most valuable cards printed
In addition to these, there are also a couple cards that were printed in extremely tiny quantities to celebrate various phases of Richard Garfield's life
My siblings and I were avid collectors, and would play the game in official tournaments at Toys R Us
Pro tip: I know its the Wild West, but be sure to return anything you borrowed from your opponents at the end of the game
You wont deck out since you cant Scry with an empty deck, but you will go right down to the wire
