One of the questions I would like to pose to my fellow tiering contributors - would you believe Landorus-I will remain broken without Keldeo forming the LandoKeldTar trio? Which of the two sweepers, Keldeo or Landorus, are the bigger offenders of this core?
I haven't been doing suspect yet, I'm into exams right now, but based on prior experience I can say that both are have pros and cons, but I think Landorus is the bigger offender here. Sure, Keldeo has Rain boosted STAB + pseudo-mixed sweeping move, but at the end of the day you can't boost your Speed without sacrificing offences, you can't boost your offenses without losing to faster things, and at the end of the day you'll end up losing to things such as Jellicent, Latias, and Amoongus, unless you run TTar and lose your boosted Water STAB (which as we all know isn't a huge deal, but it still affects Keldeo's power). Landorus doesn't have these problems, because you effectively get more power than Choice Specs while retaining the ability to switch moves and boost your speed. Meanwhile, you can't effectively wall Landorus because it can switch moves and if it happens to U-Turn to TTar while you switch Latias in, you're done. At least you can predict the switch with Keldeo. Meanwhile, at the end of a game, there is going to be one thing that can always shut Lando down, which is priority, and it had better be powerful, too.
I really do think that the problem with the core itself is how brainless it is. It makes a win-win situation for you that an opponent can't break. Its a die if you switch, die if you don't thing because your opponent can do either, and if they screw up, its generally less of an issue for them than if you screw up. But yeah, imo Lando is the broken one out of this core, not Keldeo, although I think that banning one will balance out the other a bit, just because both are really strong and once you beat one, TTar traps you and the other one can come in and finish you off without a problem, for the most part. If you're only allowed to use one of the two, though, that can't happen as easily, and fixes the problem much more easily.
So yeah, I'll probably be pro-ban for this one, once I have the time to get reqs.
