I play blockwars a lot and I have some ideas for some kits you can add.
Ninja kit: This kit gives you a potion of invisibility that lasts for 5-10 seconds.This would be great for rushing and its pretty balanced since its not the entire game and you need to take off all your armor making u pretty easy to kill.
Pyrotechnic:
This kit would give you 3 tnt when you begin, this is great for people who make giant defences that takes years to mine.
Knockback:
This kit would enchant your sword with knockback. This would make for interesting combat as people can knock each other off better.
