These are his abilities.

Masterpuff

God Tier.

In all fairness, he isn’t a god of a character. They probably will release him eventually.

Buttehrs

None. Hed be a tophy champ.

LeNoirFaineant

Without the Arc Overload regen and the buffs from the node he's just a dude with a slightly tricky SP1.

High Demi God

I would say high demigod. In the current meta, he isn't that special. Besides having decent power control, he has no specific utility. Yeah he can hit hard, probably, but I can't really estimate if it is super crazy.

High Demi God

Abilities
Sig: ISO Inversion
Special Attacks: Maestro's control over the Contest allows his Special Attacks to reverse the empowering effects of ISO-8, reducing all enemy statistics by X% for 9 seconds.

Combo Shield (Passive): When his Health drops below 75%, Maestro charges his ISO-infused armor to grant himself a Combo Shield, protecting his Combo Meter with 100% effectiveness.

Passive: Superior tactics and intellect grant X increased Critical Hit Rate for every 5 hits of the Combo Meter for as long as a Combo is maintained.

Fury (Passive): As health is lost, Maestro loses control and allows his Hulk Rage to take over, granting multiple stacks of Fury, each granting X increased Attack.

Specials
Triplicate ISO Blast
Two ISO-infused blasts from his gauntlets, followed quickly by a massive blast from his armor.
100% chance to inflict Degeneration, dealing X Direct Damage over 5 seconds.

Soulsword & Godslayer
Two swords from two powerful female warriors, now being used to cut down Maestro's foes.
Burns up to 45% of the target's max Power and inflicts Direct Damage proportionate to the amount lost.
100% chance to inflict Bleed, dealing X Direct Damage over 5 seconds.

ISO Power Unleashed
For a brief time, Maestro lets his inner gamma-irradiated self loose. He smashes his opponent, then unleashes the full power of his ISO-Gauntlet.
100% chance to Stun for 4 seconds.
100% chance to Power Lock, severing the opponent’s flow of Power for 12 seconds.

He seems interesting, with power lock + burn, degen, and what looks like guaranteed crits at the end of a long fight.
Unfortunately, there are no actual numbers avaliable
