I know as it is, the technique is pretty much voided by all. But I don't like voiding canon things if it can be nerfed to acceptable levels, which I believe this jutsu can.
I have a few ideas for weaknesses and advantages taken from the actual jutsu (and a mix of my own ideas) that could make it a useful jutsu while still not being too overpowered.
Advantages:
1. They cannot be sensed by normal means (Clones that virtually have constant Mujin Meisai)
2. They do not dispel like other clones as they are very durable (Doton: Domu durability)
3. The user can switch places with the clone(s) at any given time
Disadvantages:
1. They can be sensed via contact sensing, Sage Mode, or be seen with Rinnegan.
2. The clones can only use taijutsu
3. Only 1 or 2 at a time.
4. While active, the user cannot use any clone techniques
5. While split, so is your chakra, making it impossible to use high level techniques above B rank skills (kekkie genkai abilities, unless given a rank, are the exception)
6. If the clone is killed or harmed, the user receives half the damage.
All opinions on this are welcome, if you think it can be improved or outright ban the jutsu still entirely.
