Schema Thief

Any enters-the-battlefield abilities of the copied artifact will trigger when the token enters the battlefield. Any “as [this artifact] enters the battlefield” or “[this artifact] enters the battlefield with” abilities of the copied artifact will also work.

Each of the tokens copy exactly what was printed on the original artifact and nothing else (unless that artifact is copying something else or is a token; see below). It doesn’t copy whether that artifact is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

If the copied artifact has in its mana cost, X is 0.

If the copied artifact is a token, the token that’s created copies the original characteristics of that token as stated by the effect that created that token.

If the copied artifact is copying something else, then the token enters the battlefield as whatever that artifact copied.
