I don’t understand why you guys are shooting down the OP. He does have a valid point - this game USED to be among the cheapest but RIGHT now I’d say it’s among the most expensive so anyone who got into it because of the price, has every right to feel cheated.
You can make a competitive deck for roughly $100 to $150 in many other games, whereas in Pokemon two Shaymin and a Hoopa alone are going to set you back ~ $220, and then the rest of your deck will probably go for a decent $100 to $150. I think only MTG is more expensive than that.
Having said that, this game does have the benefit that since 90% of the big decks out there share a trainer core + Shaymin and Hoopa, your second and subsequent decks will cost a lot less than other card games as you only essentially need to buy about 10 cards, which are usually your Pokemon / Pokemon-EX, whereas in other card games you usually have to buy 40/50/60 cards all over again for a new deck as there are very few “staple in every deck” cards.
Though I do think it’s unacceptable that TPCi has let this happen. All they had to do was print Shaymin in a tin if they knew they wouldn’t release the Premium Champion pack in the west and we’d still be mostly alright, even with some fairly expensive trainer cards like Max Elixir, VS Seeker, Trainers’ Mail etc.
