Numel isn't exactly your cup of tea kind of LC Pokemon; lacks the Speed, the typing (defensively), and the sort of bulk it needs to switch into stuff. Let's look at its perks as a Pokemon:
- Simple: Stockpile
- Support options: Stealth Rock, Will-O-Wisp, and Yawn
- Good STAB options in Earth Power, Overheat, Fire Blast
What's the best way to exploit Numel to its full potential? I say Numel can run a support/defensive set despite the lack of reliable way to switch into many things and the lack of physical and special bulk.
It does have a near exclusive ability Simple to boost up both defensive stats and Will-O-Wisp to offset the lack of physical bulk it has. Simple allows Numel to not only increase its stat on both ends, but it also boosts its stats by two stages! The good part about this is that this tier lacks a reliable way to erase boosted moves. I've scratched up a theorymon set that could potentially work:
Numel (M) @ Oran Berry
EVs: 196 HP/196 Def/76 SDef
Bold nature (+Def, -Atk)
- Stealth Rock / Rest
- Earth Power
Stockpile is obviously the eye candy of this set, as it allows Numel to increase its defensive stats by two stages. After a single boost, Numel is peaking at around 25/28/24 (HP/Def/SpD) -- a pretty high defensive stat for someone with a poor defensive typing. Will-O-Wisp makes this set even more difficult to budge, when you consider the amount of overzealous physical attackers that might try to switch in. Here is just a display of Numel's ability to take hits at +2
Earthquake LO Gligar vs +2 Numel - 56.00% - 80.00%
DynamicPunch Machop vs +2 Numel - 28.00% - 36.00%
Outrage LO Dratini vs +2 Numel - 40.00% - 52.00%
Head Smash Choice Band Aron vs +2 Numel - 60.00% - 72.00%
This is just a list of potent physical attackers derived from the May stats in order. As you can see, Numel can take quite the beating after a single boost and this doesn't even count Will-O-Wisp inflicting them. Your typical scenario would be Stockpiling on something as they switch in; survive the hit, hit them with Will-O-Wisp and begin the stall. Stealth Rock or Rest totally depend on what you plan to do: Support or Stall. Earth Power is the key of this set, as it can easily eat Rock-, Steel-types, and Houndour for super effective damage.
I'm going to test this set later and see how it goes, but as for now I have a rough sketch of what Pokemon will draw in attacks for Numel to switch in and start setting up:
From the list, I can lead off with Machop to lure in Duskull, which allows Numel to switch in and start setting up Stockpile. If you're lucky, you can can Duskull staying in and you can use Stockpile the second time to reach higher levels defensively. Munchlax will hurt not you with Earthquake after a boost, if you're lucky, you can grab the second boost and start spreading Will-O-Wisp the third time around.
