Most of these look pretty meh.
Also is that a reprint of Full Heal? I certainly hope not anyway. We don't need reprints of terrible cards.
I'd have to disagree. While I think many cards are overrated, there's definitely some potential in these cards. We'll have to see how the meta turns out, but here's a couple initial thoughts.
Ninetails brings back memories of Flariados, and unlike Leafeon UL, Ninetails seems to be playable with its awesome Ability (if it's translated correctly). Ninetails also has some ample support in the form of Roserade (the UL one can poison and confuse, the new one can search for any card in your deck) and Amoongus (automatic poison and confusion). Devolution Spray, if it's worded the same way as the Base Set one, could make this deck really work. Also, if there's a way to put a 3rd special condition (burn) via Houndoom (Prime) or Torkoal, that would be 170 damage + Poison + Burn.
Even if there is a rotation, Ninetails/Amoonguss could be a very fun, if not competitive, deck.
The "good" Garchomp is nothing spectacular, but doing 60 damage for 1 energy and 100 damage for 2 energy (without discarding the Energy) seems pretty solid. What I think could make this deck shine is the built-in Dragon-type Pokemon search given to Gabite. It brings back memories of Dark Dragonair, but unlike Dark Dragonair's evolution Dark Dragonite, Garchomp actually packs a punch. If Altaria's ability is translated correctly, it would be stackable, giving Garchomp major damage potential.
I'm not saying that these cards are really, really good. I just think that we potentially have two viable decks in our hands based on those scans.
