I don't know why testing was even necessary, it's so obvious Raikou, Gallade and Frosslass should remain in BL regardless of the new rules, the tier was much more fun without them. Now everyone has them on their team, my old teams which used to do well in UU are now useless
How ‘fun’ the metagame is has no bearing on the tiering of suspects. Besides, I’m finding this new metagame much more fun at the moment, with as yet no ‘standard’ team from a pool of 6-8 Pokes rising to dominance. That may change somewhere down the line, but for now the metagame is gloriously diverse.
As for new additions and previous BLs, the only ones I’m still slightly on the fence about are Froslass and Gallade, not Raikou as I firmly believe UU has enough of the necessary tools for dealing with it, though it will always be a top-tier threat. I have not seen anything from Alakazam or Rhyperior to consider them in any way broken, whilst Umbreon wasn’t BL material before and isn’t now either.
With Gallade, he may possibly qualify for BL under a mixture of the Offensive and Support Characteristics, as while I don’t think he can ’sweep’ by himself with ease, his ability to ‘punch holes’ to make life easier for other threats should not be underestimated. I still need much more time to play against and test him more, but that is the key feature of Gallade that I am paying particular attention to this time round, and one that just failed to convince me of his brokenness last time round. As for Froslass, I also need to test her more as I personally think most people aren’t using her right at this moment in time. People are using her as a lead and often suiciding no matter what the situation, which doesn’t always work (in fact rarely works in my experience), and may well be wasting her true potential. By saving her for later, she stands more chance of acquiring that beautiful luxury that is a free turn, which can make all the difference with her supporting potential. Unfortunately, I have seen very little of this so far.
As for another Pokemon I am looking closely at, what do people think about Honchkrow now? For me, it is the one Pokemon that is looking like the most likely BL candidate right now. With a simple max Attack LO set of Brave Bird, Superpower, Sucker Punch and either HP Grass or Roost, it is incredibly potent. In a similar way to Gallade, it is unlikely to outright sweep by itself, but its ’hole-punching’ ability may see it cross the borderline by skating between two of the Characteristics. Very,
very little can switch in and reliably deal with Honchkrow, who doesn’t even have much moveslot troubles anymore, so ‘significant portion of the metagame’ easily applies here IMO. Still plenty of time for the metagame to adapt though.
