Sculpting Steel, Darksteel Colossus and Echoing Truth

[LotusHead]

My opponent has a Darksteel Colossus.  I have a Sculpting Steel Darksteel Colossus.  Can he Echoing Truth my Sculpting Steel and not bounce his Colossus? This happened, and I let him bounce my Steel and keep his Colossus in play (aren't I nice in Casual). But I don't know the answer.

Also, what is my Sculpting Steel's Casting Cost, Name and so forth after it resolves and a few turns have passed? I have Sculpted my Mishra's Factory many a time and assume it is not an artifact later on until I activate it.

When something copies something, it copeies everything.

It's as if you had actually played that card.

If you copy a DC, your Sculpting Steel no longer has the name Sculpting Steel.  It now named Darksteel Colossus.  If it gets Echoing Truthed, your opponent's DC gets bounced as well.

If you Sculpting Steel an animated Mishra's Factory, you end up with a non-animated copy of Mishra's Factory.  It functions just like a Mishra's Factory in every way including abilities, mana cost, name...etc.
