I was thinking it’s Ability would make a fun partner for the Arcanine PROMO that costs and discards 2 Fire Energy to deal 40 damage plus 10 damage for each damage counter on it. Either you soften up your opponent, or you prepare another Arcanine. On top of that, Zapdos partially covers Arcanine’s weakness. But I’m sure that deck is hardly feasible for playing through the story, and with no Colorless Energy in either of the signature Pokémon attack costs (not to mention the fact that Zapdos technically doesn’t hit an Active Blastoise at your own convenience and will OHKO Arcanine unless you attach Defender), it probably wouldn’t be viable.I used the zapdos in one playthrough (hacked my inventory) so long as I used no other Pokémon I could ohko most opponents pokemon
