uh, not really...Dusclops is a terrible mon I completely knowwhy it's nu and that's because it has no offensive presence, no good recovery, bad defensive typing, and so many more thuings that are bad. Dusknoir isnt much better but it is better. Avalugg is not good in nu due to it's papaer thin special defense. Not to mention that lilligant is handled by a fire type such as Ninestales laughably easy.

vs.
252 SpA Ninetales Fire Blast vs. +1 4 HP / 0 SpD Lilligant: 222-264 (78.7 - 93.6%) -- guaranteed 2HKO
assuming lilli already has a boost (which it probably will if you switched it in at the right time), it's definitely not laughably easy. lilligant will be faster because of the speed boost and actually probably win this battle, albeit with a decent amount of damage.
and for more fire types...
flareon is a problem, but it'll still knock off over half of its hp, which is worth something.
+1 252+ SpA Miracle Seed Lilligant Petal Dance vs. 252 HP / 4 SpD Camerupt: 433-511 (125.8 - 148.5%) -- guaranteed OHKO
+1 252+ SpA Miracle Seed Lilligant Petal Dance vs. 0 HP / 0- SpD Heatmor: 268-316 (86.1 - 101.6%) -- guaranteed OHKO after Stealth Rock
it won't OHKO rapidash without stealth rock but it will with it and if rapidash KOs with flare blitz it'll be taken down by recoil, which is again worth something.
and blah blah i think you get the point. fire types stop her a lot of the time but they don't walk away without heavy damage. the more i look at it the more bugs, flying types, and grass types i see, which are much bigger problems for her (she does still 2HKO cacturne, OHKO chatot which is kinda easy but still, 2HKO exeggcutor, etc., and bugs and flying types are weak to stealth rock though so she still has an OK time) but she can still tear through almost anything that doesn't resist her, which means if you take out anything that resists grass there's a good chance it'll be the end of your opponent. she's not perfect but i don't think she's weak enough to be tiered this low
