I honestly think this decision is pretty simple. There's no question that Sleep and Species clauses should stay. Lack of Sleep clause would enable Pokemon such as Darkrai and Breloom to dominate the metagame to no end while lack of Species clause would just be absolutely chaotic. I think the fact that even Nintendo uses Species clause says a lot. As for Evasion and OHKO, I believe it's best if we leave those unbanned and then if anyone has a problem with them after a certain amount of playtime they can speak up. But, to be honest, I don't think Evasion and OHKO clauses being removed would have an impact on the metagame.
