Don't worry, he will get a break/trial that makes him more op than minato.

If i have to guess what he will get i would say something like this:

Mystery +2: 12 units, adds ignition and +30% damage.

Mystery y+1: adds tag and breaks super armor.

Standard attack +2: +30% damage, adds ignition

Chase +2: 3x round, +7% atk/nin each time.

Chase y+1: 2x round, - 10% def/res on the targeted enemy, unmissable.

Passive 1 +2: same as edo minato about standard attacks.

Passive 1 y+1: selfresurrects after 2 rounds with +30% nin.

Passive 2 +2: gains 30 chakra every time he deals damage, up to twice per round

Passive 2 y+1: gets also a selfstacking res/def boost like kushina trial.
