It doesnt sound like a massive savings, but given the sheer volume of cards youre getting (with 14 in each pack), youre bound to get some very usable ones
Holding all else equal, we would like to invest in cards with low sentiment because they are cheaper and have a farther ways to increase if they pick up hype
If youre really dedicated to the combo, youll definitely want all the cheap cantrips like Brainstorm, Opt, Consider, Ponder, etc to find your pieces, and youll want Dispel and probably some other counterspells to protect yourself when you try to go off
Youll also see that Stellar Pokmon have attacks which cost a combination of Energy types, beyond the standard one type/Colorless that most other Pokmon attacks have
That said, Id probably advise Catchering Mewtwo in the first 3 scenarios, but Im reserved on the third scenario
Each pack contains 10 meticulously curated cards, all in English, ensuring you get the best of the Pokmon universe
