32 deck challenge

32 deck challenge

So i am currently working on my 5 mono and colorless decks. I have white [[Darien, King of Kjeldor]] and red [[Tannuk, Steadfast Second]] done though probably could use some more work but now I am moving on to the others. Which sounds more fun to work on black [[Massacre Girl, Known Killer]] (focus creature reanimation), blue [[Emperor Mihail II]] (merfolk tribal without madlab combo, green) [[The Cabbage Merchant]] (foods), or colorless [[Omarthis, Ghostfire Initiate]] (noncreature reanimation)? Any ideas are welcomed.
