Low damage output??? Due to the energy cost and the Dragonite being a stage 2 I can't say whether or not it will be meta breaking, but hitting 200 isn't that low, especially with choice band and Devoured Fields boosting the damage to 240, which is plenty atm (and that's excluding the Altaria that boosts Dragon damage by 20). As for the first attack being weaker, it wouldn't be the focus of the deck (unless the deck idea was to use the buffs mentioned before for cheap, 1 energy attacks that could 2 hit ko Pokémon, while using Max Potions to keep Dragonites from being KO'd), it's not as important to look at, considering the second attack's high damage output.
