I was kidding about boss rush >->
Wave motion cannon's fun I like it
and I forgot ties of the bretheren was cards of different names my bad, I did read the rules, that's why I thought adding one would be harmless
Nothing immediately pops into my head, believe it or not I've never built B.E.S. before >->
The only thing I can really think of is limiter removal
You could probably get away with instant fusion if you used it for tribute fodder
Oooooo Supply squad, would that work or does march of the monarchs protect them from their own effect?
Seven dark monsters, Allure of Darkness?
After testing the deck I noticed that tribute fodder isn't really an issue so scratch instant fusion, with the protection though limiter removal would be pretty good. Draw power is kind of a problem, not sure if supply squad would do much good except for coming back so maybe allure of darkness would help with that.
Something I've noticed is that the despair uranus kinda steals the show a little bit unfortunately
