If those are luck then any move with less then 100% accuracy is luck.
With a Pokemon with an evasion ability, you know that moves have less accuracy on them, and have to deal with it.
With the nerf weather's getting, I doubt that they'll be that potent.
I'd like to point out that official Nintendo formats don't have any Evasion Clause, yet you don't see people spamming evasion moves and abilities and nothing else, heck, you hardly see them at all!
Actually, you have to be very careful here.
Firstly, in Generation 5, we banned Moody, the "evasion" ability. Bearing in mind, that we banned Skymin at the same time, this test was notable for receiving a 100% ban vote, something not even Skymin achieved. Why/ Because it was at its root, uncompetitive and made the game unenjoyable. Furthermore, Ubers themselves, still banned Moody, even in a game where phazers are common, where Kyogre experiences truly massive amounts of usage (thus allowing the use of Thunder more often), on a metagame thats seems more use of Aura Sphere and so on, Moody was still banned. This actually ties into with your third point, with the weather nerf, you actually see less of Thunder, which actually removes one more check on evasion.
Obviously, there are differences between Moody and Evasion, and I am not calling them the same. Moody obviously, is far more easy to abuse than say, Double Team in that it doesn't cost a turn. On the other hand, saying that Ubers "unbanned Evasion" is not strictly true, since the premier Evasion abuser (Moody), was still deemed broken.
I would also like to point out, the Nintendo metagame is exceptionally different to ours. For instance, Doubles is potentially their focus, while Smogon tends to
tier toward Singles more often. Nintendo also often (or at least used to), limit the usage of mons that we currently deem OU or a tier below, so you have differences there as well. Go check out the BW banlist, which iirc included mons such as Mew, Victini, Jirachi and so on, as well as allowing Swift Swim, Speed Boost Blaziken, and Moody. Smogon places a higher focus on "balancing" competative pokemon. This isn't to say Nintendo's meta or banlist is 100% is bad, just that they are different (esp due to the different ban lists having a different focus). The point to take away from this is that the metagames cannot be compared, as they are very different.
As far as the methods to shut down evasion go...
- Phazing Moves: Still suffer thanks to Magic Bounce. Don't get me wrong, its a nice buff, but doesn't actually solve the problem
- Keen Eye: I don't actually know of anything in OU that would actually use this ability or even if it was worth the trouble of using.
- Weather nerfed: Both helps and hinders evasion since you no longer get to rely on Thunder if your using Rain.
- No Guard: It got one new abuser and thats it, are we really considering unbanning it just for Doublade, something thats impact on the meta is still unknown?
- Defog: This is the single change that makes me consider a test, since the move actually sees use on teams (as much as I can predict anyway).
- Minimize: Meh
- Murkrow: we had this before, didn't stop us banning evasion then, and it won't now, it sees no usage in OU.
- Clefable: We had Quagsire before, and while Clefable has better typing / movepool, it still doesn't stop a Baton Pass Chain with DEF boosts + Stored Power, the main issue.
Defog is the single change (granted, its a good one), this Gen that I could see justify an evasion retest, although I doubt it will be a priority due to most people disliking the potential abusive and un-controlling luck aspect that Evasion can potentially give, as opposed to testing pokemon that are potentially more borderline.
EDIT @ Below, Braviary is not going to see usage....lol
