I found the right strategy with Keykii's video and swapping some units around and it worked like a charm. Yes, Minerva's assassination just shredded everything, but even without her assassination it worked quite neatly. Thanks for all the tips and guides, mate. Really appreciate a friendly response.

You're right on that, mate. AW Iris did the job and more. Didn't even need her to be AW since Thetis' barely got a fight with Nanaly just wrecking everything.
