The tools stats are all over the place, the gold command block sword somehow does less damage then a regular gold sword

The iron command block sword is also somehow stronger then the diamond command block sword

This is intended

They all have abilities. And makes it so its worth using different ones

They have different effects? is there a list of all the new effects or do i just have to test them all

This is intended, each have their own unique abilities/drawbacks. They should be listed in the change log
