Replays are actually considered somewhat mandatory or at least very useful for UR noms, especially high ladder ones. I'd suggest going it like how the OU VR has you do it, which is p standard. I have no opinion on the nom itself, just want to tell you something for the nom.After reading nominations from the past few months, I see that there isn't a standard format to nominations, and replays aren't necessary. I know this is a controversial nomination, but I'd like to nominate Avalugg from UR to C- for its niche on stall. It may seem to be an unviable pick, even on stall, due to the vast amount of physical sweepers and breakers in UU that get super effective STAB against Avalugg: Mega Aerodactyl, Terrakion, Lucario, and Cobalion, to name a few. However, Avalugg can check physical attackers that don't have super effective STAB, and even some that do (like Mega Aerodactyl). It should be easy to guess what sets Avalugg can run, as it is very predictable, but for completion's sake, here's the go-to set:
Avalugg @ Rocky Helmet
EVs: 252 HP / 4 Atk / 252 Def
- Rapid Spin
Max HP and defense allows Avalugg to check prominent breakers, like CB Crawdaunt, Malt, Mega Sharpedo, and Haxorus. Avalugg can also check hazard setters that can threaten out tradition stall picks, like Mamoswine and Krookodile (the latter can cripple Gligar with knock off). While not as problematic for stall, Mega Aerodactyl is also checked by Avalugg, so you don't need a different check like Malt (which you also don't need for Crawdaunt). Rocky helmet chips away at some Pokemon Avalugg checks, and punishes u-turn from the likes of Mega Beedrill.
An alternative set with 252HP / 144Def / 112SpD and leftovers can be used to check LO grass knot Zeraora, but this doesn't achieve much else. Curse can be used over toxic to better check DD refresh Malt, and also allows Avalugg to stay in on threatening physical attackers like Terrakion and banded Infernape after a boost.
The reasoning for C- is that C and C- are reserved for Pokemon that serve a specific niche, but aren't good outside of that niche. Articuno (C-), for example, only fits on stall, and only serves to check passive hazard setters that rely on toxic to force out defoggers/spinners (like Empoleon and Swampert). Avalugg also only fits on stall, and has its niche in compressing roles as both a hazard remover and an anti-breaker. Avalugg's ability to wall Mamoswine and remove its rocks is one of the biggest things going for Avalugg, as not many (if any) other Pokemon can do this. Because Avalugg can check prominent breakers as well, it isn't dead weight against teams without a hazard setter that Avalugg is needed to check.
