One last question, why does red barely get any time-indefinite steal artifact spells when it's one of the colors associated with rogues, pirates and other thieving scoundrel types? Something like a colorshifted Steal Artifact would've been perfectly in line with red (and Hellkite Tyrant already proves it, but he's very lonely in the color), since it's functionally "artifact removal with a little extra".

One of the ways we separate blue stealing from red stealing is that blue’s stealing is permanent while red’s stealing is temporary.

I have something positive to say about the color pie. As someone who plays a lot of commander and loves red, I've seen a push in changing the color's image beyond simply "burn stuff, keep attacking." Now it has more temporary cloning, more interaction with artifacts (especially Kurkesh and Hellkite Tyrant), spell stealing (Mindclaw Shaman), draws more cards and has enjoyed a big increase in its spell-copying effects. It's more diverse, has a better late game and still feels "red." Keep it up.

Will do.
