PokePop, your analogy is completely wrong. Regardless of how the cards were obtained, all players have access to the same card pool in the rules of Pokemon TCG. Whether he's playing Luxchomp with real or counterfeit cards. Now obviously this does not get into fakes that were never printed - that's a whole other kettle of fish, and something every player and judge should call in ANY remotely serious event.
Maybe my analogy was flawed, but just as much as yours is.
The owners of the fake cards don't have access to the same card pool.
They have access to a FAKE card pool.
The either weren't willing to spend the money to obtain the real, more expensive cards, or fell for the "too good to be true" discount of fake cards and threw their money away on them instead of getting the real tools.
It's a "Trading" Card Game.
That means that you either have to trade for or collect the cards you need to make your deck properly.
My analogy was trying to get that feel of someone taking a "shortcut" to arrive at the point they need to be at to compete.
Whether its an athlete who skipped training as much but "made up for it" by using steroids, or a TCG player who wouldn't put the money/effort into getting the legitimate cards they need
