{7}: Create a token that's a copy of target artifact. That token gains haste. Exile it at the beginning of the next end step.
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 chosen artifact will also work.
If the copied artifact has {X} in its mana cost, X is considered to be 0.
If the copied artifact is a token, the token created with Cogwork Assembler copies the original characteristics of that token as stated by the effect that that created that token.
If the copied artifact is copying something else (for example, if the copied artifact is a Sculpting Steel), then the token enters the battlefield as whatever that artifact copied.
The token copies 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, or so on.
