Posting here, since it seem unintended.
Current DPP Ubers actually don't have Sleep Clause implemented, like we can see in this match, from tour 18.

(yes it is a tournament battle but there wasn't any tour rules added. Anyway,
here , another test. It chall match, and we still don't see Sleep Clause)
DPP Ubers have been
unbanning Farceus recently, but I can't see anywhere something related to Sleep Clause in dpp ubers, so I assume that it is a bug.
It is pretty relevant to DPP Ubers, since Dark Void Darkrai was already a huge threat with Sleep Clause but without Sleep Clause, Darkrai become the threat #1 of this metagame with for example Nasty Plot/Dark Void/Substitute/Dark Pulse forcing run thing like Vital Spirit Primeape just for this.
It would be nice if it is possible to fix this!
