PvP Arena - Minecraft PE Maps

So I made a quick little PvP map where you can Fight your friend and just PvP, it is my first time messing  around with Command Blocks so I couldn’t figure out how to refill the kit chests so you can use each kit 3 times.

It’s a 1 v 1 pvp arena with 3 different kits, after the first person dies both get teleported back to the choose your player room. then stepping on either pressure plate will take you to the kit room, where you can click on the ready button once you are ready, where once the other player also presses the button,you’ll be teleported to the arena  with a 5 second countdown where you can fight.

This was made in like 3 days so I can  play with some friends, so yea
