Add the kb boom boxes to bedwars. 
They would cost 1 emerald each, making it a mid-game item, like ender pearls. Then we. would have the ultimate kb boom box, which would cost 8 emeralds, and would have the same behavior as in skywars. (Isn’t self-only)
Ultimate kb boom box
regular kb boom box
and add snowballs like treasure wars
No. I do agree that they should come back, but 1 diamond does not make it a mid game item. Considering that chain armour can be bought just after killing your side rush. I also don’t agree on the ultimate kb boombox being only 2 emeralds. They should be at least 5 to make it fair.
I see no reason to add ultimate kb boomboxes but I’d love to see block breakers and normal kb boomboxes back in bw at some point
Amazing idea I voted!
