Yes, I know this is a ran 8 with 3 materials. But this is like OTK stuff. Untargetable, force all your opponents mons to attack it (which is like 2000+ damage each anyway), and then you can always attack directly. It's like an alternate win condition. Needs drawbacks / toning down.

Well I added that you must skip your BPs
