Does Roaring Skies Altaria (#74) have a Hidden Ability?

Question

I have a card in my collection that is kind of odd to me. I want to know if this is something like a hidden ability or something else. I have an Altaria from Roaring Skies. Here is the cards information.

STAGE 1
Altaria
HP 90
Colorless
(Here's what I think might be a hidden ability)
4 Evolution: You may play this card from your hand to evolve a Pokémon during your first turn or the turn you play that Pokémon.

(Ability): Clear Humming
Each of your * Pokémon has no weakness.

** Wing Attack 30

Weakness: Lightning x2
Resistance: Fighting -20
Retreat: *

This is not the only Pokémon I've seen in TCG with this kind of "hidden ability" (if that's what it is) like that. So my question is, is this something like a hidden ability? If so, is there a special way to treat it or does it get used just like any other ability?

Comments

It is sufficient to specify only the card number and expansion, since we can look up the card details ourselves: https://bulbapedia.bulbagarden.net/wiki/Altaria_(Roaring_Skies_74)

OK, sorry, I'll keep that in mind.

Answer 1

Ancient Traits are special effects given to certain Pokémon, starting in the Primal Clash expansion. They are not Abilities, and as such, effects that would prevent Abilities from activating (such as Garbodor's Garbotoxin or Wobbuffet's Bide Barricade) do not apply.

Your Altaria has the Ancient Trait Δ Evolution. It is not an Ability, but Ancient Traits occasionally bear similarities to them (but with fewer preventative measures, as seen above).

Thanks Willowisp! I didn't know these existed.
