Saheeli Raji

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

As Saheeli's last ability resolves, all three artifacts enter the battlefield at the same time. Triggered abilities of any of those artifacts will see all three entering the battlefield. Replacement effects, such as that of Sculpting Steel, won't see the others on the battlefield as they are being applied.

If the copied permanent has {X} in its mana cost, X is considered to be 0.

If the copied permanent is a token, the token created with Saheeli copies the original characteristics of that token as stated by the effect that created that token.

If the copied permanent is copying something else (for example, if the copied permanent is an Altered Ego), then the token enters the battlefield as whatever that permanent copied.

In a Two-Headed Giant game, Saheeli's first ability causes 2 damage total to be dealt to the opposing team.

The token copies exactly what was printed on the original permanent and nothing else (unless that permanent is copying something else or is a token; see below). It doesn't copy whether that permanent 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.

The token is an artifact in addition to its other types. This is a copiable value of the token that other effects may copy. Haste and the ability's delayed triggered ability aren't copiable.
