I think I'd rather trim my powers to something more managable. Complete Arsenal seems more like an end goal, rather than something I'd want to start with. After all, if you have everything, what's next?
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.
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.
