I do not really know if this is an improvement from my first UU team (which I may post if people would like to see it), but it feels like one. I just started UU a day ago. But this whole team centers on Raikou and Heracross with protection from Shaymin and Bronzong as they take care of their weaknesses.

It looks good,but has a heads up,you have a weakness to Jolly Nature Choice Scarf Heracross,as the only thing that can take a hit is Bronzong (which may be 2HKOd if it has any Moxie boost on it). And even though Houndoom can outspeed with a Scarf attached,its only a check and not a dedicated counter since it hates Stealth Rocks and can be KOd by a Close Combat. Moving onto Houndoom,a Choice Scarf looks like it limits its overall coverage a little,and it has small coverage with 3 Dark type attacks.

Another Houndoom set to try is

Spoiler:

It has slighty better coverage,does what Snorlax does,has a chance to OHKO things with Pursuit like Chandelure with the EVs.

Also a Defensive Regenerator Slowbro can replace Snorlax. It can take Earthquakes,Close Combats,even Mega Horn if its at full health and counter with something like Thunder Wave or Psyshock.
