First off, yes. Slowbro gets the team support that it needs to make it broken. There is a precedent for this. ORAS OU decided that Mega Sableye was broken at the end of Gen 6 and banned it. This gen, they banned Dugtrio and realized that the combination of Dugtrio + Mega Sableye was what made the metagame broken and thats why there were calls to unban Mega Sableye and retroactively ban Duggy from ORAS OU. In a metagame with Dugtrio, Mega Sableye was considered broken. In a metagame without it, it was fine. Same principle applies here with Mega Slowbro. Also Tentacruel is 2HKO'd by Azumaril Knock Off.Yes, those mons are good for team mates, but does having teammates make a mon unhealthy on their own? You're basically saying that mega bro is unhealthy to the tier because we have mons that are good with it. Besides, "Everything is going to have it's checks" is pretty much the reason to why Mega Bro isn't like other current BL mons, like Buzzwole and Staraptor. Not everything is going to have it's checks. And unlike, for example, Azumarill that can 2ohko everything on the tier bar Tentacruel with coverage moves, Mega Bro suffers from 4mss, which means that in order to carry a third move, it is most likely going to lose to mons that have good def/spdef.
Next, isn't the sheer unpredictability of Mega Slowbro what makes it so dangerous? It can be running any set, so how can you switch it in reliably. If you guess the set wrong it can setup and then you lose the game.]
So your idea of a check is one that depends that there is nothing already put to sleep and that if there isn't that there isn't a 1 turn sleep? Sounds like a pretty terrible check to me.Breloom has a chance on 1v1ing it with Spore on the 1st turn, then hitting it with Bullet Seed on the following 2 turns (i'm assuming a sleep roll here, though)
Whats the issue with relying on teammates to deal with its solitary weakness?That part is true. Latias is the only cm user who has recovery in roost, but aside from her, everything else lacks it. However, my point there was to show that there is no CM user right now that has a way of dealing with toxic aside from having cleric teammates.
Who cares that *this* Pokemon checks one set and another Pokemon checks another? Not only are there not very many things that check Mega Slowbro period, I can't think of anything that can counter all of Mega Slowbro's possible sets. For the S and A ranked mons, there are dedicated checks or counters that will beat every conventional version of the Pokemon, not reliant of the set. Mega Slowbro would undoubtably be too much for the tier to handle and I don't condone any form of suspect test or unban.You didn't understand what I meant in my post. I simply showed what mons can check *each* Slowbro Mega set. Sure, there aren't MANY things that can check it, but there aren't MANY things that can check any S rank/some A rank mons either, and they aren't unhealthy for the tier. (with the exception of Azumarill imo, but Azumarill isn't the point of the discussion here) I believe a suspect test can show whether Slowbro Mega is too much for the tier or not.
