I think a good idea would be adding a FVDisco Map. FvDisco is a redstone creator. He makes one of the most awesome maps. But I would suggest adding "Cake Defence". It is a cake and you survive rounds of mobs. When the round is over you buy items to protect yourself. Maybe a the Sonic map FVdisco also did. Just my idea.

 

I support, He's really good at his stuff.
