After many months of testing and badly losing locals. I got 2nd place with this deck.
Reasoning:
I decided the focus of the deck should be turboing Lucemon into chaos mode with blue card or going from chaos mode into leviamon/X/statan mode with blue card.
Meta has too many dedigivolving effects running around. Paying 6 memory evolutions for a card that gives your opponent the choice to delete something is painful as they can just dedigivolve you and call it a day.
Leviamon/X has very strong security removal which give the deck much needed speed to get you to the Satan mode board kill at 0 security.
I removed cherubimon Ace and replaced it with Seraphimon Ace as while it can play a Lucemon for free. Its DP minus doesn't come up too often in any meaningful way. Seraphimon Ace gives the deck access to non deletion removal which can be very beneficial against red and purple decks. On top of which he becomes another target for shadowseraphi Ace.
Reduced Gospel of the fallen angel to 1. At this point the card's only purpose is for me to evolve into Satan mode if all of my copies end up trashed by Lucemon.
No Lucemon X as it has too many restrictions. Requires to have a Lucemon in name in sources, requires both players to have security for protection, and still susceptible to dedigivolving. Also if you run him you need to make room for seventh divine Cruz which is usually a dead card in hand as you almost never meet the color requirements and a point where you have less security than the opponent has digimon.
