I think it would be worth trying out a LO Durant with hone claws/rock slide/iron head/x-scissor. It is very similar to aero except Durant's attack stat sky rockets with a single HC due to hustle, and very little can stop him from my experience. If the other team does not have a scarf fire type or a steel type, then durant will most likely rip the other team apart, or dent it or than enough for stoutland to come in. Slowbro, Suicune, Gligar, Nidoqueen, hitmontop, etc. are all either 2HKOed (even hitmontop with intimidate) or OHKOed. Blastoise can easily come in on any fire attack. If you want, you could use light screen on alakazam over maybe grass knot (because I assume it is the least used attack, and durant can 2HKO suicune while aero can't I don't think?). Since you have hippo and stoutland (and also durant possibly) to take physical attacks with ease, light screen would help make those 3 almost invincible, if alakazam is about to die or you have a free turn. I'm still getting used to UU so I can't offer much more advice but I've been using durant and sweeping teams without even knowing what I'm doing half the time.
