I mean that's great and all but I guarantee you future comments from now are gonna arbitrarily replace mons one after another just to open themselves up to newer threats. Like removing Slowking for Rotom-W for example puts all the pressure of a Keldeo switch in on to Dragalge and that's just asking for a Clefable sweep to come in afterwards because Dragalge gets worn down quickly and from the looks of it that's your real Clefable answer there. Then you need to consider that the team has ways to net hits on this obviously but gets picked off little by little from any Gengar + Conk core because the sets are extremely easy to read, granted it's a foundation so not a huge deal. M-Bro just sucks for the team to because you're relying on a ton of luck in getting in M-Absol safely which is an enormous risk in taking Scald + burn chance + the fact it might already be boosted. You sort of beat this with Clefable if you somehow let a crummy player let Clefable get to like +3 or something or M-Absol to +2 but let's be real that's not happening unless they lost something important or are completely new to the game. The moment Clef + Absol are out of the picture Defensive Chansey wins, which is pretty embarrassing as well so that needs to be taken into account when you have a mon that is prone to be worn down by defensive cores and another that is worn down by offensive ones, M-Absol and Clefable respectively. Little things like Heal Block Klefki, Rock Slide Lando-T (use this, your TFlame check right now is relying on a move known to miss......), Dragon Tail Dragalge to pass around poison affliction to help M-Absol late game sweep, those are things you should think about.
I didn't really follow the thread to much so obviously didn't read any thought process in why people chose things but when I build I picture scenarios in my head that will benefit me and ones that will beat me, when I take into account team changes and team builds. Sort of a given you have to use the team in practice to get an idea as well but giving yourself a harder time against such a common threat is silly. I overlook stuff all the time though so it's not a huge deal but that's my perspective on this team right now you guys should ponder over.
