This is a purple base of SoC. I was doing some theory crafting today and came up with this list. I am not sure if it is any good but I have success with it as of right now. I prefer the Dex Program deck I posted prior. Instead of going over the different combos I will go over the pros and cons. The Purple Base has the BT 14 Loogamon. This can give you a lot of memory and can recycle your Eiji. The Black Base has the BT 16 Dorumon which can get your Kosuke in play quickly and add more protection to your stack. The Digi-Egg are up next. The Purple Egg is Bowmon. Bowmon can help you digivolve from trash easily. This sets up combos with your Dex Digimon. For some reason it isn't once per turn. The Black Base has any of the Dorimon eggs. Preferably the BT 16 Dorimon which can give you memory even on your opponents turn.
The Black Base has access to DORU-Din and other powerful Black Option cards that aren't easily accessible in a Purple deck. The Purple Base has access to Mist Memory Boost which is an extremely powerful Memory Boost card. The Purple Base can also make use of the Tyrannomon more often. The Black Base has more protection and removal while the Purple Base has more recursion and swarming potential. All in all the variant you go for is up to personal preference. I happen to own more cards for the Purple variant which is why I posted this. I prefer the Black Varient due to its removal.
