Not sure how you'd trim, since Power Immunity is part of the package. I'd probably just use my favourites and ignore the rest.

I agree with ShadowMonarch212

Hmm...having every single power is...boring. I'd probably seal away (or maybe give away) most of my powers, and keep a select few. Immortality, Animation, and Personal Gravity. Because...living forever is awesome, animating things is a versatile ability, and I want to fly.

I'm in the minority but if it were me personally, I would keep every power because it could come in handy.

I would seal most  of them and just keep absolute wish, then if there is a problem... just wish the problem away. this tactic is as smart as it's lazy

No. I would seal any power that would threaten my individuality, straight-up discard any magic powers and keep the rest. If it's a universe where other people also have superpowers, advanced technology, magic, etc., I'd use Real World Enforcement on a universal scale, then do as described below using Telekinetic Force Manipulation.

Running rampant in the world, spreading chaos and destruction everywhere you go for your own enjoyment while laughing at the utter futility of any attempt at stopping you?
... What? That's what Absolute Restoration is for.

Well as its complete, Meta power Manipulation is part of the package so, just seal the ones that would make you feel like you don't have free will like Omnichronal Perception and use Power Level Manipulation to decrease the level of the rest so you can grow/evolve with them slowly. However don't be an idiot and seal away an important defense power. Make sure to keep Psychic Immunity, Absolute Invulnerability, Absolute Immortality, Erasure Immunity, Soul Anchoring and Power Anchoring etc... At least that is what I would do.

You have Complete Arsenal, youre literally the embodiment of omnipotence. Complete Arsenal is an expression of omnipotence; to have all powers. You are immune to any and all powers including meta power manipulation, etc. Why and how? You have every power, including all immunity powers and powers that allows you to exist outside of reality. You could be like Ajimu Najimi and attempt to create a story and try to thwart yourself, although she failed and tried to kill herself because she couldnt accomplish nothing. She spends trillions of years attempting the impossible again and again and succeeding again and again, she kept attempting the impossible hoping that she would fail, because she realised that she was in a manga. Just a thought, although according to her, "If you want to become a junk character like me then come find me."

I would keep all of them, and if any of my friends want any I would make great use of Remaking. Mindshifting and Perspective Designing would be tantamount to my state of being and lie at the forefront of my powers. After all, all the frightening aspects of CA and it's threatening our free will could simply be done away with by a simple change in perspective.
