Instead of buying random cards, consider focusing on a specific set, Pokmon species, or type (for example, Shiny Pokmon , Full Art cards, or only Gen I Pokmon )
Even if you wanted to play a standard game with this, the only fun part is mixing 3 differnet decks of your choice together, but the unfun part is the lack of good cards to pull you into the game
This along with delirium is often why midrange decks run cards like Seal of Fire or Tarfire as ways of quickly dumping extra card types into the graveyard
Since the developers chose to make opponents have more thematic decks, they have to incorporate cheating mechanics in order for them to be viable
While collectors can buy up a lot of cards, the big issue affecting inventory right now is scalpers buying out as much product as they can find in order to flip it for a profit
The most money ever spent on a Pokmon is $5.275 million, but most of the top cards are in the $1,000 to $100,000 range
