During turn #2, coldsteel6G played Zapdos onto their Bench. Was that Zapdos looked like this?

(Zapdos (Pokémon GO 29/78). Pay attention to its Ability.)

Its Ability applies to all of your opponent's Basic Lightning Pokémon (except this one and other Pokémon named "Zapdos"). Therefore, Miraidon ex's attacks do 10 more damage to your Active Pokémon (because it's Lightning-typed) so that Miraidon ex can Knock Out your Roaring Moon ex in only 1 turn.

Hope this helps!
