That suggests Expanded format play won't be available in Pokemon TCG Live until sometime after the app launches
And this is combined, for example, with healing cards, usually with heavy Pokmon that depend on 4 basic energies or more, like Charizard VMAX DAA 20, or those Pokmon that use special energies like Mewtwo & Mew-GX UNM 71 to replace them using the Scramble Switch , using healing cards like Acerola BUS 112, without losing those energies
I dont know how this works online, but if the cards in the pack populate in the game theres some REALLY good stuff in here
