I hope you like these, I am pretty good with coming up with good kit names and accessories so I can almost always make a good kit :)
You added a pickaxe with efficiency 10.
In that case, why should you add stone blocks if you have a great pickaxe like that?
You can't build up, because because the opponent chops blocks under you!
