Any "enters" abilities of the copied artifact will trigger when Sculpting Steel enters. Any "as enters" or "enters with" abilities of the chosen artifact will also work. For example, if Sculpting Steel copies an artifact creature with sunburst, the copy will get +1/+1 counters based on the number of different colors of mana used to pay Sculpting Steel's total cost. If Sculpting Steel copies a noncreature artifact with sunburst, the copy will get charge counters based on the number of different colors of mana used to pay Sculpting Steel's total cost.
