Haven't really uploaded these types of stages, however I'll probably do the Advents. Anyways, this run is okay, actually wanted to keep aiming for better less clutch runs, but this will do. Note that this stage actually has many lineups, so not all these units are mandatory to beat this stage. You can certainly make do with slight changes to units.
Anyways this strat is pretty precise and you really need to know Clionel timings and what exactly to do in certain situations to get a winning run.
Sniper Cat was added as it can make some parts much less precise, and also makes the last rush to Clionel nowhere near as clutch.
Try your best not to mess with the timings, as they mess with other timings, or how things play out in the stage, but note that some bad luck can happen in your runs. Things such as Trolly Blogger procs, or more importantly Sleipnir procs can mess with the run.
As for the actual strat, at the very start spawn one Maglev, then once he hits the base turn off Sniper Cat. Then spawn in another Maglev as soon as you can, with a Hyper Mr. also sent in around the same time. Once they die off, lure to the base and spawn in one Maglev. When Maglev dies from the Angel Gory, instantly have a Ramen and Manic Macho Legs ready to take his spot. Now you want to do the usual Clionel first Bahamut timing here and rush with Maglev as well. Sniper Cat helps here so you can turn it back on for a brief moment when killing the first Sleipnir.
Now for the rush part, you want A. Bahamut, Ramen, Yulala, and Hyper Mr. all in the LD when doing the first rush. Maglev should also be sent for this, but can die whenever Clionel gets knocked back and he's sitting in Backswing. Yulala is Trolly Blogger clearer, and Hyper Mr. helps kill any Trolly Bloggers that would potentially get in the way when you knock back Clionel. Ramen is for decent DPS while also being good at tanking the second Sleipnir.
You should have knocked back Clionel at least 3 times. Once this is done do not spawn any other units, and instead full lure the set of two Angel Gories. Then spawn in Ururun + C. Gross while having Ramen be your meatshield for this phase. This should be just enough to kill off the Angel Gories right when Clionel starts hitting the base. Note that you can actually push a bit too hard so try not spam Ramen too fast on this phase specifically.
After this, it's the last Clionel rush, and you're basically doing the standard Clionel Cat Cannon timing to get rid of this Sleipnir and get through Clionel's LD. I actually hesitated a bit on this part and almost lost by not spawning Bahamut faster than I should have. Here is where Sniper Cat is very helpful in keeping Clionel from destroying the base faster than usual. You can interrupt her attack and give yourself more time to kill her.
After that it's basically more of the same Luring and then switching between Ururun/Yulala/Bahamut to deal with the remaining Sleipnir and Angel Gory phases. That's the main reason Research Combos are used here, helps my Ramen frontline actually stall the Gories very well without them pushing super fast.
