Looks kinda cool, but what's it's main wins?

If Diamond Dude pulls out a Oja. Delta Hurricane or Megaton Magical Cannon, then it activates the next turn and kills all of opponent's cards. Clear field, unless they flip a Waboku in your standby phase/beginning of mainphase.

I'd throw in a Destiny Signal, so when your Big Eye dies, you can arrange the cards and pull a Diamond Dude.

Thanks for the fix naru.

I'll try that out, but with Royal Decree in here I don't want to run too many traps.

If you feel like having some extra fun with Diamond Dude, use Law of the Normal. Blow up both players field and hand, leaving both players topdecking just after having Diamond Dude set you up with another spell waiting to be used.
