This set is beyond horrible :/
Very, Very few playable cards. Only Brock's Guts, Starmie, and Dragonite-EX, and Mewtwo are useable, and everything else ranges from gimmicky to bad.
- Beedrill is cute in theory but getting 4 of these out at a time is going to be next to impossible, even with turbo trainers, especially since it takes more than 1 turn to power up.
- Combustion Blast Charizard is nice, but in Fire decks it's mostly worse than Volcanion and Flareon-EX anyways. The rest of the Charizard cards are almost completely useless, taking too much setup for a middling reward.
- There's no reason to use M Blastoise-EX over Primal Kyogre-EX when the latter has unblockable self-acceleration and a more damaging attack.
- Why is Staryu's attack called "Lightning-quick punch"? I doesn't have hands! (This is more funny than serious)
- Electrode is exclusive to Lightning decks. I'd rather use Magnezone over it because you don't give up a prize and the ability is more than once-per-Electrode, which makes it much more useful in the long run than blowing yourself up once.
- Zapdos takes way too much setup to be practical. I'd rather do 3 for 150 and discard all of them with Pikachu-EX than 4 for 170 and discard all of them with Zapdos.
- Seriously? They print Nidoking /again/ but not Nidoqueen? We have a Nidoking that requires Nidoqueen in Steam Siege, but they still refuse to print a Nidoqueen? And if you really want to poison, use Dragalge BKP. Less deck space and less time for more reward.
- Haunter, Drowzee, and Koffing but not Gengar, Hypno, and Weezing. They could've printed us Venusaur and Blastoise lines to match the Charizard line, but no, they'd rather give us useless NFEs.
- Just use Shatter Shot Mewtwo-EX. Heck, even Photon Wave could give this a run for its money.'
- Mew would work if it had a good attack or free retreat, but even then it's really weak to Hex Maniac because of the low HP.
- No Sandslash, so this basic, Ken Sugimori-art Sandshrew is useless and could have been cut to give us more Venusaur or Blastoise to keep up with this oh-so-exalted Charizard.
- Having to put 3 Coloured Energy on an effective Stage 3 with no acceleration means that Machamp BREAK is worse than Zygarde-EX every single time.
- No Steelix, but Steelix did debut in a later gen so I guess it makes sense. Doesn't mean I like it though.
- No Clefable. I guess they needed a Fairy Type, but if they wanted one they should have cut something else for Clefable, not just throw in Clefairy and hope we forget about it! Metronome would have been a little bit useful if it costed a DCE, but they thought of that, too.
- Pidgeot-EX is like a less threatening Darkrai-EX or M Audino-EX, and M Pidgeot-EX... does damage, I guess? Too much setup, not enough reward.
- Rattata and Raticate are interesting, but Rattata only discards off the active and is shut off by Garbodor, meaning it fails as a form of tool removal. Raticate could work, but with Special Charge roaming around and most decks running Basic Energy these days, it came a bit too late to have any real use.
- No Dodrio. For all the Evolving basics that were printed without their evolutions (Excluding Onix, Chansey, Tangela, and Porygon), we could have fit in the full Stage 2 Venusaur, Blastoise, and Nidoqueen lines, and still have an additional space left over.
- All the Trainer cards save for PokéDex and Super Potion were in the format already and see next to no play. PokéDex doesn't rearrange enough cards for Max Elixir and is only 1 more than trainers mail, and Super Potion is inferior to max potion for the most part. Spirit Links are only as good as the megas you can play them to, and none of these are particularly good except maybe Venusaur.
- Misty's Determination is still useless.
So yeah, that's my thoughts on the set. Too much Charizard, Too many unfinished evolution lines, and very few of the cards are even playable, let alone good.
