I got a cool idea earlier and it's something that could be used to unnerf stuff.
The MeepTraders come every month(?) and sell different things, what if there was a type of MeepTrader called "Magical Trader" or something. He could sell little powerups. Here's a list of powerups and what they could do.
Magical Emerald(emerald item) - Right clicking a villager with this will allow it to breed. (you have to have 2 of them for 2 villagers to work)
Flaming Snowball(fire charge item) - Right clicking will send a small fireball in the direction you are looking. Does not damage blocks or set fire to blocks. Will set fire to whoever it hits(only in PVP zones).
Arms(stick item) - Right clicking an armor stand with this will give it arms.
Animation Gem(diamond item) - Right clicking an armor stand with this will make it change it's pose into a random pose. This item has 3 uses.
Radio(disc item) - Right clicking opens a GUI where you can select any song in the /warp club main room. Infinite uses.
and whatever other ideas some people have. Most of these are destroyed on use. Costs are up to admins.
