Those are two individually cool effects. I feel though while they superficially synergize they don't work together quiet as well as they should.

I realize the tokens make further copies of your Equipment extra cheap to cast, but in a sense the activated ability also is a nonbo in totally circumventing the first ability since you already have access to as many token copies of the Equipment you need. Drawing additional copies of the card becomes redundant. The abilities are add odds.

Maybe try to instead pair the first ability with " : Scry 2. If you scry an artifact card that shares a name with an artifact you control, you may reveal that card and put it into your hand." to feed into the cost reduction (less interesting if you want this to be a commander).

If you think of this as a commander I'd instead change the cost reduction ability e. g. "Artifact spells you cast dost mana less to cast. Equipment spells you cast cost an additional less to cast."

I like: "Artifact spells you cast have affinity for Artificers." But that may be random riffing.

Third option: To tie the two abilities better together alter the activated ability to benefit from the same cost reduction: " : Create a token that's a copy of target Equipment. This ability costs less to activate for each other permanent that shares a name with that Equipment on the battlefield."

This is certainly a cool idea and gives a real sense of industrial revolution through a mechanical representation of mass production.

I don't know whether there is also an intentional flavor of industrial espionage. It is a little at odds with modern design philosophy, but can be made to work here.

Yeah, originally the first ability was only for equipment spells rather than all artifacts; I changed it partway through design, but forgot to change the mana cost afterward.

Not sure what happened with the ability; originally it was just going to cost with no color in it at all, so I must have been an idiot somewhere along the line while I was changing it.

Not sure if this is correct wording for it, but it should work with Furnace Layer as well as Goblin Test Pilot.

EDIT: Updated wording so it works with Raving Dead too.

Realized this in the Cube According to Gatherer part 6? While scrounging around for ways to hurt Chameleon Colossus I realized that Magic will never intentionally combine Human, Zombie and/or Spirit, so I made a card that something bad to each of those types individually, and ultimately something really bad to any changeling that accidentally had all three types. A really mean silver bullet that I eventually chose not to use.

Should this specify non-zombie? Doesn't make sense to infect the infected, also prevents loops in the mirror

Well, yes, but they removed human exceptionalism from most of the class types like wizards and clerics. I guess if zombies were "human zombie" it would screw up human tribal.

This is deliberate. "Zombie" with no race type implies "zombie human". "Zombie Insect" or "Zombie Bird" or whatever is used to diverge from the norm. Yes, this is blatant human exceptionalism :)

I'm assuming because white loves Equipment. The active ability should probably require white mana.

I can see this in Mono-, to be honest. What's the justification for the double white?

Equipment should be capitalized. Neat card though. I could definitely see it in an Eggs deck.
