One of the first Base Neo decks I made myself and I played on TCGOne all the time. Unsure of the ratios at the moment, might change them later.
The idea is simple and straightforward. The synergize really well with Wigglytuff, fixing math for it and just sitting on the bench afterwards to power up Do the Wave. And of course, the bats more often than not are going to be doing a lot of the work for you, taking out your opponent's Cleffas. Really the gym can be anything, its just there because we need to bump things like Sprout Tower
In all honesty this is probably just a worse Sneasle Bats. But I didn't want to play Sneasle Bats, and I also didn't want to build Wigglytuff the traditional way with Muk sitting on the bench.
