Looks like the gimmick sets for every OU mon is finally coming to fruition (also made a gimmick set for every UU mon, but that's not important right now).
Darkrai's main issue normally is dealing with steel types, as it has to rely on focus blast to hit them, and there is a reason it is called focus miss. This set alleviates this issue somewhat with the physical drain punch that can chunk a lot of steel types. This of course is worse than special darkrai, but that fact alone can be a benefit to it.
At +2, darkrai can reach an attack stat of 558. That's just a few points lower than proto attack roaring moon's attack stat, which is known to be powerful. Knock Off gives good dark stab while being a good progress making tool for Darkrai. Drain punch helps with steel types while offsetting LO recoil a bit by giving darkrai recovery. The final slot is quite flexible. Poison jab is standard to hit fairy types super effectively which otherwise can somewhat wall this set, Rock slide can hit some mons such as Zapdos, Volc and Gouging harder while not proccing the burning affects of the later two and Sucker punch can give Darkrai valuable priority to hit faster targets such as Deo-S and Dragapult.
The Tera type is also somewhat flexible. Tera poison is more standard to resist fighting, fairy and Bug type moves while boosting the power of poison jab, Tera fighting keeps your dark resistance and can boost up Drain punches power and Tera Dark can be used alongside Sucker punch to give Darkrai extremely powerful stab priority.
