At its core, Tentacruel really is a UU Pokemon. It got to OU via usage to begin with, so once it fails to meet the usage standards, it'll be nothing more than a homecoming.
EDIT:
Donphan can't 2HKO shit with Assurance, much less Dusknoir. The damage calc automatically assumes 100 bp for Assurance, which is stupid and completely inaccurate. Dusknoir is just gonna Pain Split and Will-o-Wisp your ass.
Drapion and Absol will be rendered ineffective 70% of the time they come in and Drapion is outdamaged with EQ even if it misses, so you might as well pack a Lum Berry or not even bother trying. If you want to try and take out Dusky, what you need to do is have a Arcanine come in and pray the Flash Fire boost lets you OHKO before he fires off EQ. Moltres works too. Other Fire types get EQ'd and if that doesn't KO, Shadow Sneak. Azumarill could get behind a Sub once it thinks it's safe but again, don't come in right away or you'll risk a Will-o-Wisp.
Tbh, Dusknoir might pull another Cress by being better than everything else in its respective type (it dumped all over Alakazam, Hypno, Grumpig, and Espeon for sure), but as far as walling most of UU, it can't do that by just coming in and sitting there. You might have to fool around with certain sets to see how UU takes it before you make any solid assertions about whether or not it really belongs there.
EDIT:
whoa, so much wrong here, don't even know where to startAs for Dusknoir imo he would be a change (big change if you will) but nothing that would be monumental. The usual wall breakers like blaziken are still able to break through him (Fire blast being a clean 2HKO), while he fails to OHKO back with eq + sr damage (provided he invests the usual 28 ev's in attack).
As for the spin blocking matter he still gets thrashed by the usual counter to anti spinners (ie:Drapion and Absol),who 2HKO with their respective dark type attacks . Donphan 2HKO's dusknoir with assurance and sr damage with lefties factored in and so seeing that donphan's faster , provided you get him on the switch , dusknoir wont even be able to burn you.
