Bulk up scraggy is p bad, use DD instead. Drain Punch>Brick Break all day. Crunch as a secondary STAB and Zen Headbutt or Ice punch for coverage, or HJK for more power.
Shuppet is way to slow to use Taunt because it will only hit 15 speed with a + nature. You are wanting to drop that speed even lower, down to 9. You can't even Taunt Hippopotas with that. You can use Pain Split to heal though and it's legal with the DW ability.
I was debating on the move, and alrdy decided to replace it. Here's the new moveset:
Shadow Sneak
Payback
Confuse Ray
Disable
I don't like Pain Split because she cannot hit first, being able to be defeated in the turn.
If it can't live to Pain Split, how is it supposed to Disable something?
Duskull does this better. It is bulkier and has access to Shadow Sneak as well as Will-O-Wisp (which, in Little Cup, is far superior to Confuse Ray).
Basically the only reason I can think of to use Shuppet over Duskull is access to Knock Off, but even then, Shuppet is not really bulky enough to make good use of this.
Duskull? Alright, I'll work on that. Thanks! What do you think of this kind of moveset for an upcoming Duskull?
Duskull, Male

Does Wailmer really learn Yawn, like it suggests in that analysis's Other Options? I can't find any source that says it does, although I think in the past there may have been some source that had it incorrectly, since PO's team builder it has Yawn as well.
You can always use those EV wings to give those, which is probably the easiest (though still annoying to collect). It is still definitely posible, however.
I'm not an expert on it exactly, but I hear that it was proven that any EV spread was available using power items and extremely weak Magikarp with lots of switching to minimize EVs. Back then level differences didn't affect experience points so it was doable.
Edit: I also just noticed the question about the Little Cup Doubles, and I don't know people that play it, but it should be theoretically possible in a simulator as well.

Would an Eviolite Tirtouga work?
