CB Darm cannot handle Suicune or Slowbro. CB Guts Hera can handle stall quite well but gets revenge killed even easier because most of the offensive tier is stuck in 85-115 speed tier and Heracross is at the bottom unlike staraptor which is in the middle. CB Victini can definitely handle stall (except Grass + Water bulky cores like Chesnaught + Slowbro/Suicune or simply bulky Rocks) but the problem is common offensive mons can [sometimes] even switch on it like Scarf Hydreigon and Mega Amph [if mega evolved] and finally, Shao, hits like crazy w/ CB and can fuck a lot of non-scarf HO but it's stopped too easily, Sableye, Crobat, Slowbro, etc.)It's really amusing to see people complain about a wall breaker...breaking walls. Slap CB on Mienshao, Victini, Darn, or Heracross, and you have yourself something even Suicine can't stand up against. Band set is so easily taken care of if you have anything remotely fast (think, raikou, infernape, mienshao), and the scarf set hits about as hard as reckless scarf mienshao, with less speed. Weak to rocks, prone to recoil, and having a very predictable movepool doesn't help it. I am more scared of seeing an enemy Victini, for fear it could be scarfed, banded, mixed, LO, or ebelt.
Staraptor, however, is only stopped by 3 mons, Doublade, Rhyperior and physically defensive Rachi and maybe 252 HP / 252+ Def Mega Aggron but few people run that.
This is why I think NP/Mix LO Nape + CB Raptor = fucks stall and most of non-scarf meta.
NP Nape can OHKO Rhyperior w/ Grass Knot and Fire Blast decimates Doublade, Rachi and Mega Aggron. If you don't want to die from recoil against bulky ground/water then Grass Knot can do average 60% (LO 252 SpA) so you take less recoil.
Furthermore, looking at megas, Mega Ampharos stands out as a teammate for Raptor, 1. because it can take on most of HO (All sets of Tini, All sets of Darm, all sets of Entei, all sets of Crobat, Sash Zam, All sets of Infernape) and sometimes scarf shao 2. because it also helps whether down bulky waters 3. it adds to the Volt Turn core and 4. because it provides Heal Bell support so = fuck sableye
I'm talking about my good old RestTalk/Volt Switch/Heal Bell Physically defensive Mega Amph
it can also counter Scarf Shao 3/10 of the times if rocks aren't up
252 Atk Reckless Mienshao High Jump Kick vs. 252 HP / 252+ Def Mega Ampharos: 172-204 (44.7 - 53.1%) -- 28.1% chance to 2HKO
tl;dr: Special/Mix Nape w/ grass Knot and LO + CB Raptor + Phys. Defensive Mega Ampharos = fuck meta / really good balanced team.
That's just my reflection of playing so much UU the past 2 days (nothing to do in summer lol)
