Most Commander decks try to circumvent the singleton aspect of the format by including cards to recur things from the yard
And once youve figured out their worth, be sure to protect your prized cards
For example, your opponent could cast Burn from Within (a spell with mana cost XR) with X equal to 3, but not with X equal to 2
Therefore, it is quick and practical to put them on the field and use them for their Primal Turbo ability, where they can attach up to 2 special energies from your deck to one of your Pokmon, charging Lugia with the Powerful Colorless Energy DAA 176, where the Colorless Pokmon it is equipped to deals 20 more damage
Right now, this card is selling for a price which is impressive even by the standards of other mega TCGs like Pokemon
So, anyone selling Pokemon cards is entirely at the mercy of the market
