>>20502731You're scraping the bottom of the barrel with those choices. I never thought I would tell someone that Greninja is the best thing on their team.
Volcarona doesn't have what it takes to be used in OU right now, at least not without a massive amount of team support. This isn't Gen 5 anymore, Volcarona isn't scary at all.
Carbink is just a poor man's Azelf (which is a poor man's Deo-S, but that's banned). I wouldn't suggest a suicide lead on most teams, but if you really need to use one Azelf is better with a similar set of Timid 252 HP 32 Atk 224 Speed. Mew is also pretty great with that set (252 speed 4 atk though), but Azelf outspeeds more than Mew can and hits harder with Explosion. Honestly, you would be better off with something that can get rocks up at any point in the game like Ferrothorn.
Hawlucha is pants, and so is the Unburden mechanic altogether. Use Talonflame as a revenge killer or Terrakion as a fighting type setup sweeper. Going fast is great, but wasted speed is not.
Diggersby is decent, though I would almost always choose something else instead, especially with that set. Diggersby has a potent Quick Attack but you still want to outspeed things before you get OHKO'd which it will even with HP investment. You might want to try Mega Medicham for a similar mon to both Diggersby and Hawlucha.
Ampharos is great in UU, and quite the addition to a bulky offense team, but this is most certainly not a bulky offense team since nothing can switch into things. Rotom-W is usually better than bulky Mega Ampharos in OU since it has enough bulk to take hits, the ability to switch into EQ, and decent recovery in ChestoRest or Pain Split. This Ampharos set will just be a sitting duck in most OU matches.
My tip: stop trying to make BL mons work. They usually don't work without massive amounts of team support. If this is your first foray into competitive just stick with the good stuff before branching out. You'll learn more about battling that way.
