Glare? Thunder Wave? Moar like Stun Spore. If we're going to go for paralysis, any of these moves would be fine.
I support Will-O-Wisp as well, it does a great deal to blunt the defensive threats to CAP4, especially Skarmory, which likes its HP, its Sturdy, and the ability to threaten with Brave Bird, all of which go out the window with Will-O-Wisp.
One move that isn't on our lists is Psycho Shift. I of course brought it up long ago in the context of Flare Boost, but I still like it. The last move I think would be noteworthy, especially for how it interacts with Weak Armor, is Cotton Guard, which makes Aurumoth very physically bulky while also giving it a "stockpile" of Defense boosts to utilize.
[17:53] <&Deck_Knight> If I Cite and Prune CiteandPrune's post, what does that make me?
[17:54] <Birkal> a citeandprune cite and prunner
[17:54] <%DHR> O_o lol
[17:54] <+Mos_Quitoxe> Cite and Prune doesn't do enough of either
[17:55] <+Mos_Quitoxe> can we make him change it or force him to pay damages
[17:55] <&Deck_Knight> It would be a lot easier for him to Cite and Prune if we made him a mod.
[17:56] <&Deck_Knight> I delegate this task to Birkal.
