Can the "Standard OMs" mega-rule include Evasion Abilities Clause and maybe Evasion Items Clause? Out of the 6 tiered and permaladdered OMs, 4 of them (Balanced Hackmons, Shared Power, Godly Gift, Mix and Mega) have at least some restriction on evasion abilities and items. I assume that the tiered permaladdered OMs represent the most popular OMs within the community, so having a majority of them taking action against evasion seems to me that neither OM councils nor the OM community really believes that evasion is ever healthy for an OM.
The argument by UT in #12 that "In most OMs, giving up your item or ability for a 10% chance is not worth it" is absolutely true, but this treats evasion more as a "broken" element, rather than an "uncompetitive" element. From the "uncompetitiveness" viewpoint, a random 10% or greater chance of your move missing can turn easy wins into ridiculously unfair losses, which is unpredictable and lacks any skill whatsoever. Furthermore, in OU, all forms of evasion are banned, despite the vast majority of Snow Cloak and Sand Veil users being unranked and Bright Powder being an obviously terrible item for most Pokemon. While you can argue "OMs are different than standard tiers so we shouldn't necessarily follow their rules", how exactly do the vast majority of OMs change/nerf evasion to the point where it should still be allowed? I don't believe they do.
I am using the permaladdered OMs as my evidence because OMOTMs rarely have evasion strategies develop severely due to their inconsistency, time restriction, and the general focus on more "broken" threats. However, the permaladdered OMs have virtually infinite time for any meta developments and are overall more balanced, which I believe allows evasion strategies to develop there more often.
