Hm... this feels like nobody would play artifacts because they wouldn't get that artifact at all... maybe just allow it so both players get a copy, then, artifacts can stil be played, but are risky.

Just an idea. This is a cool card.

I should include a clause so it's only when you would create an artifact token. This only affects artifact tokens, so you'd need both artifacts and things creating artifact tokens to work.

Neat!

I read this wrong before, somehow I read it as:

Whenever an opponent plays an artifact, you may create a token copy of that artifact instead.

that's why i commented what i commented.

I don't understand what this does?

It lets your artifact tokens enter as copies of other artifacts rather than what they would normally be.

You can't target inside a replacement effect, and you don't need to exclude the source of the replacement effect, so you can trim some of the words from this.

"If you would create an artifact token, you may create a token that's a copy of any artifact on the battlefield instead."

-or-

"If an artifact token would be created under your control, you may have that token enter the battlefield as a copy of any artifact on the battlefield."

Or some fusion thereof.

It lets you make Icy Manipulators and Whispersilk cloaks instead of treasure tokens. (Or wasps)

It's a very cool concept.
