Since no one ever makes an official decision in these sorts of threads, I guess I'm just going to unban Z-evasion until someone tells me not to.
I spoke with Zarel already, but ftr

Evasion Clause will be defined as: A Pokemon may not have the moves Double Team or Minimize in its moveset.
If any Z Evasion moves turn out to be a problem in specific tiers, Tier Leaders may deal with them in whichever way they deem fit. If they become a problem a cross all tiers, Z Evasion moves might be included in the Evasion Clause. No reason to globally ban elements that have never been properly tested.
