Swords N Mobs(Pvp Minigame)

This is my attempt at command blocks so this was mainly a practice

This is a Minecraft Minigame where there are 2 teams of 1 or more who need to battle it out and kill eachothers kings
The kings are too powerful to be killed by a sword so you got to push them into a pit of lava
to gain victory

But with what gear?
Kill mobs to get xp to build your set of armor

Gamerules:
Mobgreifing = False
commandblock output = False
Natural health regen = False
Gamemode = Adventure
