More food for Drago, but Haxorus definitely feels a bit late to the party for it.
230's solid, and there's no option that hits damage above 230 that doesn't either compensate with energy loss or limit attacking next turn. But, 240 is a relevant damage benchmark to hit now, and 260-270 is becoming more apparent too. With Ogrepon as an energy acceleration engine, it's probably still just more consistent to use Giratina to cover that stuff in the middle, else you got a bunch of Drago fodder that begins cluttering the deck. It's certainly an option at least looking at for that, and should be considered if damage benchmarks ever change in favor of it.
Drago having an option to cover special energy is cool... if the one matchup you cared about that right now didn't also pack Mist Energy. You'd still need Temple of Sinnoh on top of that. Ugh.
That fraxure with Omega Barrier is great, just like Unified Minds Axew was. I'd just hope we eventually get a Haxorus that can carry its weight offensive by itself to go with it.
