Hey Invictus, here's some suggestions from a fellow Danger World user:

Switch out Eagle for Demon Slay Barrier. Not only can barrier protect your weapons, it can stop your monsters from exploding as well. Especially for Black Drake when he's a size 0. Plus Eagle can't stop Inverse Tenbu from removing him first and then exploding the weapon. Consider squeezing in 3 barriers in somehow.

Naga for Barbed Wire/Double Guillotine. I feel that Naga just lacks the defensive oomph to stop massive crit weapons from punching through, even against the likes of Kaizerion, its supposed nemesis.

Battle Spirit Unite...well depends on your meta. You only have the 2 Omnilords as your movers to reliably cast it on, but the more experienced players I've faced tend to ignore Iblis since they know how easy to replace he is. If you're facing control heavy decks that focus on killing your side monsters, then 4 BSU is great. But if you're up against aggro decks then maybe replacing 2 BSU for 2 Divine Crash will soften the damage you take.

If you're serious about using Demon, put in 2 Little Drake to get him into the weapon's soul.

And lastly, slot in 1 Invigorating Breath. Never leave home without it.
