So Ambipom functions badly as a lead then? Good luck trying to argue that one.At d2m:
Your arguments were almost ALL irrelevant, except for one which proves my point further.
Electrode is the only Pokemon you listed that has a niche in the lead slot of a team. All of the other Pokemon you listed DON'T function well as leads. The "overall (all of the reasons it was banned add up to this)" reason Froslass was suspected and banned was because it forced you to use a Scarfed Sleeper or Crobat to stop spikes from getting up first turn. This fulfilled the support characteristic in every way, because either it fills the support characteristic from setting up Spikes, or it fills it by forcing you to use a Scarf Sleep move first turn, which is easily avoidable with Chansey everywhere, meaning it could just set up spikes later while you have no chance of doing anything at all.
On top of this, it can spin block for itself so Donphan being able to spin is a pretty argument, especially when it gets Rocked by Ice Beam. Otherwise it has to come in after spikes are set up and take a ton of damage while trying to spin...Good Luck with that. That's the sprinkles on the icing I guess, considering I already said Snow Cloak was the icing :)
EDIT:
I also think Rhyperior is being 'underhyped' again. I don't want to list the calcs (I did a lot last night) so you can just believe me or do them yourself, but with the right EVs in the Sand, Rhyperior 2HKOes Milotic (252/252+) 47% (I think, it might be more...) of the time with an unboosted EQ, while also not being OHKOed by Surf (even after a Sub). So Rhyperior can come in on one of the millions of Pokemon it can come in on, set up a Substitute, let Milotic come in, and spam Earthquake on it, and possibly even 2HKO it. This opens up a hole for a shit ton of Pokemon.
Taking Rhyperior down in the Sand is going to be next to impossible without Milotic as well.
I agree that d2m's argument is pretty irrelevant, but what is even more irrelevant IMO is MS trying to argue Taunt / Ice Beam mindgames in Froslass' favor. That shit goes both ways, and almost always serves to go against Froslass because it makes Froslass' main job (Spikes setup) more uncertain.
As for your Rhyperior in the sand argument, don't forget that Sand requires a specific strategy and set of Pokemon to work well, especially in UU. And if you were arguing for Rhyperior having suspect-worthy power under Sand (though I don't think you are, and you shouldn't IMO) then that says more about Hippopotas being Suspect worthy rather than Rhyperior.
