Notes & Combos
The idea is to burn you're opponent to death with Nightmare Archfiends and Rising Rebellion Falcon. 6000 from RRF, and 2400 from Nightmare Archfiends is enough to win instantly. You can consistently get Nightmare Archfiends into rotation thanks to Noir Lanius' level modulation effect being able to make your level 4 Raidraptors level 3. You then make Cherubini to dump Lilith, Lady of Lament, who you'll revive with Muckracker once you're done with your Raidraptor set-up to avoid the fiend-lock. Lilith will then tribute herself to get one of your 3 copy of Nightmare Archfiends. If you hard draw the trap instead you can just do your normal combo and surprise your opponent with the instant-kill.
This version of the deck is not as good as a standard variant obviously, but can still do most of the same things. We don't use Fuzzy Lanius because the archetype lock is antithetical to what this build aims to accomplish, but can be run anyway if you just pivot away from the pseudo-FTK and play the deck normally. The strange handtrap ratios are just meant to provide Crossout Designator targets.
I wouldn't go out of my way to craft anything just for this specific combo but if you have all the associated URs already it couldn't hurt to try.

vs ririn. This is an example of the full combo taken back when I was testing it a while ago.
