Just for fun, I decided to see if Primarina's Harmonics (LOT 67) would work with pokémon with Ancient Trait Alpha Growth (for example, Whiscash, (Primal Clash 20)). Both of these do the same: allow another energy card to be attached, when I attach one from my hand.
What happened was that I was only able to attach one extra energy, as opposed to two, if I read these correctly.
Now, some of you might instantly jump and say: "But they both state that cards attached via abilities or effects don't count!" And I get that. But I don't mean that extra card magically attached via the effect. I mean the one I attached at the start.
My thinking goes like this: I attach an energy card to Whiscach. Its Alpha growth says "hang on, I just had a card attach to me! I will allow you an extra one". Meanwhile, at the same time, Primarina's Ability says "Oh wait a minute, trainer just attached an energy card to a pokémon! Give him another go". And as a result, I should get two extra cards.
Think about this as a number game: Whiscash stands up when he hears me saying a number divisible by 2. Primarina stands up, when she hears me saying a number divisible by 3. And then I say 6. They should both stand up at the same time on the first go.
Or am I thinking wrong here...? I know that two Harmonics won't stack. But these two look like they should.
Actually... by my reasoning, Harmonics should stack as well. One energy card - we're still talking about the same, first card I attach from hand - can activate more than one effect, can't it? If my opponent had Gengar from Crimson invasion and Frozen City, I would get 4 damage counters in total whenever I attach energy from hand, wouldn't I? If so, why can't two Harmonics activate at the same time?
Nothing on the card states it can't. Unlike, for example, Jungle Totem on Shining Legend Venusaur, which specifically states that only one of these abilities can be active.
