The problem is that Inconsistent teams seem to need an over involvement of counters to stop and even then can still potentially screw you over somewhat consistently regardless. When pathetic things like a Bidoof (a bidoof???) 6-0 an OU team, the ability is BROKEN. If something like this can't be considered for banning, we might as well call Arceus and Kyogre OU since they can be "countered" with the right Pokemon after all. After all, Swords Dance Arceus will be walled endlessly by Skarmory and Kyogre has only average speed.
Just because it has counters does not mean it is not utterly broken. By the logic used to accept weird things like "it has a counter, it is totally okay!" even though 90+% of the players despise it, the only way to justifiably ban something without a doubt now is to have like 150 in all stats (cause 120 stats are totally average!) and the ability to do everything and Magic Mirror or something. Cause that seems to be what it takes (a little exaggeration but it is really hard to convince some people of obviously broken things, like the people who call for things like Lugia and Ho-Oh in OU).
Haze: Use every other turn or else it will start being problematic again. Resorting to Slaking (Truant) now? Most Haze users aren't that great or will be worn down eventually.
Perish Song: This only forces them out. The useable number of Pokemon that can do this are pretty small and are usually off better doing other things. And devoting multiple slots to things like Murkrow clearly is problematic. Since Inconsistent Pokemon have a team, all they have to do is wate to Perish Songer is dead. Especially fun to use Shadow Tag to trap the Perish Songer in and watch it die (Wob).
Foresight and such moves: Evasion clause and for the most part aren't great. Waste of moveslot in almost all cases.
Roar/Whirlwind: Can miss and evasion has a thing of making them miss. Especially Dragon Tail which will be walled by Substitute. Ingrain Passing from Smeargle.
Toxic Spikes: Poison Pokemon and Rapid Spin.
Clear Smog: Small restricted list of users and the Shroom is the best user. Has to beware of boosted moves like Flamethrower (+2 Octillery almost ohkoes max hp 128 SDef Calm Nature and will with Stealth Rock) and Ice Breath if they get the attack boosts.
Unaware: Most of the users suck. Quagsire would rather have Water Absorb, Clefable dies to Toxic now without Magic Guard and isn't all that great now without it, and Bibarel lol matching but you'd rather have Bibarel be Simple or Inconsistent if you're using it.
And INCONSISTENT POKEMON ARE NOT ALONE. They have a team of 5 others to help and when 1 Inconsistent Pokemon forces measures to uses multiple cruddy Pokemon or moves that have no other purpose, they already have the advantage! That is enough to justify a ban, especially when it is a +2 boost every turn, free without needing to use a dang move other than Protection! Accupressure is not broken because it takes a move, has limited users, and most of the time will not give the right boost but when you have every free turn to get boosts, it is BROKEN. And it isn't just +1, it is +2! What were the game makers thinking? (No one ever knows, they make the most bizzare decisions regarding certain Pokes like making some ridiculous and some completely useless.) Sure every now and then, it will backfire, but more often than not, it will give enough of an advantage to completely destroy the opponent or exhaust them the rest can.
And Smeargle getting it and Baton Pass? Seriously? That is just cruel.
I think it is time for an ability clause, after all, we have move, evasion, sleep, pokemon, ohko, etc clauses and ban uber Pokemon. And Inconsistent is an uber ability when it turns sucky Pokemon like Bibarel, Octillery, and Glalie, into monsters that can wreck things that should have won.
And it isn't just evasion that should be worried about. If it gets the defense boosting, they will get tough to beat by attack and attack boosts are troublesome as it can deal some heavy damage to all the Haze/Roar/Smog Users and multiple boosted moves will take them out and that would leave nothing to stop the Inconsistent users.
