Given the learning curve, even if you turn around and tell me that your daughter, your wife, and yourself are all adults, you might consider getting some of the Theme Decks from the past year or two, and just using those against each other, without altering them. It isn't perfectly balanced, but the PTCGO has a Theme Format, which only allows Theme Decks (and even then, not those that include multi-Prize Pokémon or other advanced mechanics). If you don't know what the PTCGO, that's the Pokémon Trading Card Game Online. It is a free-to-play online game from The Pokémon Company, and it actually lives up to the term. You cannot spend money directly on the PTCGO; you can redeem Redemption Codes you get from Redemption Code Cards you get in booster packs, Theme Decks, gift boxes, etc. Otherwise, you can just play and complete in game challenges (including winning in general XP) to earn in-game rewards.
Anyway, I am saying it is a decent way to learn the game, and even a decent way to play online. Even if you're not interested, it can help to know that there is a small market for those Redemption Code cards you'll be getting when you buy unopened product from the last 10 years.
It is also how I know that the
- Relentless Flame
- Torrential Cannon
- Soaring Storm
- Laser Focus
- Towering Heights
- Unseen Depths
- Rillaboom Theme Deck
- Zamazenta Theme Deck
- Galarian Sirfetch'd Theme Deck
- Charizard Theme Deck
are all reasonably well balanced against each other, at least in the Theme Format.
Theme Decks aren't good for Standard, Expanded, or Unlimited Format play. For new players, it lets you learn and play the game without diving into the deep end of designing your own deck or grappling with advanced gameplay elements. Theme decks are
not built the way competitive decks are; they're still 60 card decks, but will usually have more like 20 Pokémon, 20 Trainers, and 20 Energy cards.
Competitive decks for the Standard and Expanded Formats rarely come out like that, having fewer Pokémon, fewer Energy, but more Trainer cards. 15-30-15 is more likely, and even 10-40-10 isn't uncommon, give or take a few cards.
You will get some cards useful for Standard and Expanded, though. Usually nothing
too hard to get, but sometimes pretty important (like Professor's Research).
