Why is Dusclops a tier higher than Dusknoir, its evolved form?

Question

Dusclops is UU, while Dusknoir is RU. Is there a reason for this?

Comments

weird never knew that

neither did I until I started building a mono-Ghost team, which is why I asked

Answer 1

The reason is because of the Eviolite.

Dusknoir has a max of 405 for either defense, while Dusclops gets a huge max of 591 for either defense, due to the Eviolite raising Dusclops' defenses by 50%.
This makes Dusclops a very sturdy wall in UU, better than Dusknoir due to it's superior defenses by a long shot. The only roles that Dusknoir plays that Dusclops can't are the role of a bulky attacker or a SubPunch set, which are outclassed by other Pokemon in OU and UU who hit harder or have a better movepool to choose from for coverage along side of Focus Punch.

Thanks, I forgot about the Eviolite

eviolite doest affect dusknoir cause it cant further evolve so it be 305

Sorry, that was just a typo

Answer 2

Well, I myself use Duskclops, and I believe it is because of Eviolite, the amazing item that gives a great boost to Defense stats, making Duskclops way more bulky than it's evolution.

Hope this helps!

Answer 3

In September 2020, Dusclops was untiered, while Dusknoir was in PU. This is mostly because gen 6 introduced assault vests, gen 8 introduced poltergeist, and both made Dusknoir a viable offensive tank in PU. Additionally, Drifblim (which gets strength sap now) and super Gourgeist (which didn't exist in August 2013) are better ghost walls than Dusclops.

However, another DLC was released in October, which means this answer will probably be outdated in less than 3 months.
