Just a comment on the theme, I really like it, but have you considered also trying the theme with Sakashima of a Thousand Faces as commander? I know it would restrict you to blue, unless you partnered him with another commander, but I feel like the clone mimic of Sakashima fits Kakashi better (solely in my opinion). If you're attached to your colors you could even partner him with Tana, the Bloodsower .

Once again, I like the theme

No I haven’t considered it, I’m new to edh so I’m not aware of a lot of the commanders. Those seem sweet! I’ll definitely consider those two.

And thank you, I hope to build this deck in the future.

I like the flavour here, pretty fitting. May I suggest Progenitor Mimic as an additional very powerful clone? Also, how about Moritte of the Frost to be able to copy non-creature permanents? Finally, Spitting Image is just busted with Kakashi. And considering the fact that Kakashi should be able to copy himself, Sakashima of a Thousand Faces and/or Helm of the Host seem great.

Finally, Wild Ricochet basically is a red counterspell with added value.
