Zombie-Diva used to be my war deck a bunch of formats ago, and I have to tell you, the Zombie-World version of the deck is less efficient than the no zombie-world/Il blud. I would take them both out. Il blud is slow.
You have 3 diva's, but you don't have a 4th target. Add one. I run spined gilman (sometimes reese the ice mistress, Blaze uses lost blue breaker).
I don't see your extra deck, but make sure to have leviair (brings back your banished zombies or your opponent's monsters you banished with book of life) and Gachi (for diva).
I play book of life @ 3 cuz it's just too good (but that's my personal preference, people like it at 2).
I play tours. Why? Leviair
Pain Painter not that good.
Where's the pyramid turtle? Need it at least @1 if not 2. Especially if you're keeping Il blud.
Creature swap in Zombie decks is pro. More reason you need those turtles. I don't play swap, but if you do, put them at 2. They're amazing.
If you wanna give it a shot with my way of playing, here's my deck list (with sides and extra too; I couldn't trim it down to 40, works fine at 42 though):
- Spoiler:
ill upload more today well my new deck i always make new decks everyday
