Oh man, I have been really busy these past few days, so, just like last CAP, I will not have time to finish up a movepool of my own, though I would still like to give my opinions.
Personally, I do not like Hurricane for Mollux. I think it is inferior to Thunder in most ways when they are separate, and just adds bad flavor in addition to restricting Thunder itself by making it not a TM move, and thus having illegalities. Outside of this though I think most sets have every offensive move I care about, and there is nothing other than Hurricane that I really have a problem with in this department.
Next, I think Mollux really needs Recover, and should be allowed to have it on any set. There are a few other main moves I want, and while I don't care if everything can be used together, I think Mollux should have the option of using Recover with any other given moves. This means I only really like movepools that have Recover as a level up move, or as an Egg Move but with no illegalities with key competitive moves. Due to the commonly chosen egg groups though, the former is much more common.
The other moves that I really want for Mollux are Stealth Rock and Rapid Spin. While I don't think it is a big deal whether or not two to be available together, I do think it would be ideal if they were. These, along with Recover are key to giving it a nice supportive role, and not just forcing it to power along offensively.
Overall, I think competitively my favorite movepool is Korski's. It has TM Thunder, Level Up Recover, Rapid Spin and Recover legal together as egg moves via Kabutops, and plenty of other cool moves, along side the necessary offensive coverage. Now, I will admit, I am not much of a fan of Korski's flavor. Endure, Wish and Confuse Ray in Level up don't really make sense to me, and I am no fan of some of the egg moves, but eh, nobody's perfect.
