Theres a lot to learn if you want to get into a card game, but the financial barrier to entry is relatively small, especially in Pokemon
To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as that of Volcanic Salvo)
If you cast it from exile, you also get to destroy an artifact or land controlled by each opponent, so its a brutal way to punish the whole board
Tag Team GX Cards Featuring multiple Pokmon in the artwork, these unique cards are rare and quite powerful, which allows them to command higher prices
