"artifact you cast this cost 3 less to cast" doesn't sound like the type of ability I would put on a common. Nor would copying cards - and this card looks quite wordy plus it has an obscure on board combat trick. Is this meant to be a rare?

Visionary seems like it would be a "nonmechanic" most of time in that it seems trivial to make it always trigger. I suppose you wouldn't get them off if you tried to mana accelerate into them with rituals and such but that's hardly an issue for a two-drop. How often would it be that players would have to choose between triggering Visionary and doing something else? It just doesn't seem that likely to me.

Visionary is a nonmechanic most of the time and it along with Maestro are what I consider to be this sets biggest flaws. I have no solution. I was lost for artistic or feeling mechanical ideas. I also don't have abandoned interest in forcing low-complexity.

This was always meant to be common, but I didn't think about the larger picture. Artifacts in this set ain't hot, so I wanted a bigger push to play them. Unless someone went hard for the Gargoyle tribal I forced in, there's too many other artifact creatures that could come out for free. I think less would probably be fine.

The tap ability I'm a bit more hesitant to change, because (in the world of the set) I think it's probably fine in the set. The most likely choice based on volume would be an Eye token, a 0/1 that depending on your field you be able to do something with when you cast an instant or sorcery. The 1/1 warrior and flying bird tokens are decent stalls if you've really got artifacts to squander or close a pinch. There are two strong tokens, but they don't come out cheap, so at best you'd be trying to stall out until this can win.

I don't if you know about this custom set, but there's this "Aenyr" set with pretty solid design which I think this will, perhaps unfairly depending on how you look at it, prolly going to get compared to since it also has "art" as its main theme - it will at least in my mind. Additionally, it has not-too-shabby set of mechanics (set introduction & full set spoiler) Resonance with multicolor themes is extremely strong design wise IMO. Reknown is kinda take or leave it.

In any case, if you weren't aware of that set, perhaps it could function as a source of inspiration in some part here?

Design for this set has finished; I only come back to adjust individual card flaws. This isnt a dig at Aenyr, just that it's too late in the game.
