Ok, I'm trying again with the Kit PVP questions. Here's an explanation of what I'm trying to do: My friend and I have our own server. The main part that we're working on right now is the KitPVP section. We have I think 10 or 11 kits so far. You start out with two which are Brute and Stinky. The others are locked. We already have the maps under control but the main part we need is a way to get the actual kits. I already made it so when you kill another player you get an emerald and we have an emerald storage system. I was thinking that in the KitPVP lobby, there would be a villager which is modded to sell ways to get the kits. Eg: a key to unlock some chest or box which have the kits in them. I also need them to refill after someone takes the kits out of there. In our Happy Wars section (based off of the console edition event) we have 40 command blocks that use /replaceitem to instantly give the users classes. Something like that might work for KitPVP only it would take a long time and would have to have some way to unlock them. Hopefully this counts as "what I have tried" because there's not much else I can really do. Does anyone have any ideas for me?

I was thinking that in the KitPVP lobby, there would be a villager which is modded to sell the keys to the locked shulker boxes (which have the kits in them). I also need them to refill after someone takes the kits out of there. Basically, I need a way to make it so when they take the kit out, they can't take another kit unless they want to replace it, but then I also need a way so the shulker box automatically refills after they take the kit out of it.
