All right, this has gone on for far too long.

This is the replay from the Inverse daily of jeran v. Kl4ng (aka Stockfish). Both teams are running Chanlugg, Mew, and Tangrowth. This battle could have gone on much longer but Kl4ng forfeits at turn 30.
Anyway, I'm tired of that core on every single team. I'm suspecting Chansey and Avalugg. Mew if we need to also.
Inverse doesn't get a lot of plays. I have a feeling the redundancy of the battles is a big reason why. There just isn't a ton of diversity because that core is so damn effective.
I'll make a decision after a few days or a week, depending on the feedback I get.
I'll start off by saying that since jeran had outplayed me and killed off My Volc counters that the battle in question would have kept going on around 10 turns if I put on maximum resistance.
As for the Avalugg suspect, just...no. Your intentions are in the right place, but banning it would incur
horrible consequences. Like a every team would need to run Mega Slowbro level of disastrous (even then it's still going to have huge problems compared to Avalugg). I mean, Mega Slowbro is the only other significant physically defensive thing in the tier that isn't weak to Normal. To reinforce my point, please read through the link below and count how many of the Pokemon in the top 30 for highest defense stat are weak to normal:

I'm a nice guy so I'll save you the trouble.
23 out of 30 are them are weak to normal, 3 of them are Ubers, and one of them is Avalugg. That leaves 3 remaining, and the trend of rock/steel types dominating the list continues further down.
So barring Slowbro, let's see how those other Pokemon take on, say, Diggersby:
252+ Atk Choice Band Huge Power Diggersby Return vs. 252 HP / 252+ Def Torkoal: 184-217 (53.4 - 63%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Choice Band Huge Power Diggersby Return vs. 252 HP / 252+ Def Cloyster: 153-180 (50.3 - 59.2%) -- 75.4% chance to 2HKO after Leftovers recovery
252+ Atk Choice Band Huge Power Diggersby Return vs. 252 HP / 252+ Def Cresselia: 205-243 (46.1 - 54.7%) -- 9% chance to 2HKO after Leftovers recovery (Not in top 30 but it's cress)
This isn't even considering the fact that Slowbro and all of these Pokemon except Cresselia have complete shit typings.. Like, you need Slowbro despite the bad typing to have a sliver of a chance against normal types. Every other physical wall is pure garbage.
And no, Diggersby is not the broken one. Here are some calcs on Cresselia from other renowned physical Pokemon, that, while not necessarily normal type, will be able to wreck shit without Avalugg. Keep in mind apart from Slowbro this is best physical wall there is:
252+ Atk Choice Band Reckless Staraptor Double-Edge vs. 252 HP / 252+ Def Cresselia: 232-274 (52.2 - 61.7%) -- 97.7% chance to 2HKO after Leftovers recovery
252+ Atk Guts Ursaring Facade (140 BP) vs. 252 HP / 252+ Def Cresselia: 238-282 (53.6 - 63.5%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Toxic Boost Zangoose Facade (140 BP) vs. 252 HP / 252+ Def Cresselia: 220-259 (49.5 - 58.3%) -- 66.8% chance to 2HKO after Leftovers recovery
252+ Atk Pure Power Mega Medicham High Jump Kick vs. 252 HP / 252+ Def Cresselia: 246-291 (55.4 - 65.5%) -- guaranteed 2HKO after Leftovers recovery (I assumed a neutral hit to prove a point, normally cress is just OHKO'd)
TL;DR: if you want to ban Avalugg get ready to ban a ton of stuff because this Metagame will take a gigantic turn for the worse without it. It will make STABmons look like a stally tier. Seriously.
As for Chansey,
I find banning Chansey absolutely ridiculous, as it is barely any different to its OU counterpart.
