First of all, while absolutely true that it’s another augmentation of cart mechanics, freeze clause only exists in a single gen because freeze is so broken in gen 1 that the only alternative to a freeze clause is essentially banning all offensive ice moves except Aurora Beam, which is absolutely ludicrous. This isn’t remotely comparable to the concept of banning sleep moves.
Second of all, kindly do not presume anything about me without asking me. Me personally, I have
always opposed Sleep Clause as it is implemented, and honestly, I kind of dislike Freeze Clause too even if I know why it can be argued to be a necessary evil. However, there is nothing necessary about Sleep Clause. It is a mod that doesn’t even achieve the goal it was originally set out to achieve.
Third of all, our own OU council member
xavgb has gone into extensive detail
here,
here, and
here about why sleep is being brought up now, why Sleep Clause is being talked about as an issue specifically, why Darkrai is not considered the primary issue, and how Iron Valiant, Red Card Amoonguss, and Lilligant-H also continue to abuse sleep in a problematic fashion. You should really do some reading on the sleep threat we just had that ran for 17 whole pages before making claims that have already been refuted multiple times in said thread.
