I feel like the lower ranks are so disordered currently that there isn't very much point in discussing them. I believe we should do the rank by rank system that the OU viability thread did, where we can sort out just two sub-ranks at a time. This will focus the discussion more, instead of just having random discussion here and there on Pokemon people bring up. I can see many B+/- Pokemon that could be moved around, but no discussion will ever happen on them until we focus the discussion more on specific sub-ranks. The discussion has somewhat slowed down lately anyways.
Also, I'd like to propose moving M-Absol up to A+ rank. M-Absol is a very underrated threat in the UU meta currently. It's fantastic coverage and very useful priority in Sucker Punch allows it to be an excellent late-game cleaner, and if it is able to set up a Swords Dance, it can plow through many teams. It also offers highly useful utility through Magic Bounce and the ability to Pursuit trap threats such as Mew, Victini, and Chandelure. With its unchanged paper-thin defences, you would think that it is highly difficult for M-Absol to set up a Swords Dance. However, with Magic Bounce, M-Absol can set up on literally any defensive or utility Pokemon. Also, I am unsure whether this is a glitch or not, but on PS, M-Absol's Magic Bounce activates on the same turn as mega evolving. This is a huge plus for M-Absol. As we all know, M-Absol still retains it's slow speed on the turn of evolving, which is unfortunate. However, I believe that M-Absol definitely deserves the ranking of A+.
TL;DR: M-Absol, propose A+ rank, good coverage, useful priority, Pursuit trapping, Magic Bounce on turn of evolving. However, paper-thin defences, speed on turn of evolving.
