Clone of Mechtitan Core
If I clone Mechtitan Core , say with Sculpting Steel, then activate it to make the token, the clone of Mechtitan Core will exile itself, but when the token leaves the battlefield will Sculpting Steel reenter the battlefield able to recopy the original Mechtitan Core that's just been sitting there? (you can see where I'm going with this).
Accepted Answer
Where Mechtitan Core's first ability says "all cards exiled with Mechtitan Core except Mechtitan Core", it means all cards still in exile that were put there as part of paying for that ability, except the card that Mechtitan Core becomes in exile (even if that card isn't named Mechtitan Core) (C.R. 607.1c, 607.2a). Here, in the text just quoted, the second instance of "Mechtitan Core" refers to a particular object by name (see also C.R. 201.4).
Thus, if you exile Sculpting-Steel-turned-Mechtitan-Core and "four other artifact creatures and/or Vehicles you control" with that ability, the text "all cards exiled with Mechtitan Core except Mechtitan Core" on that ability means only the cards that those other creatures and/or Vehicles become in exile, to the extent they're still in exile.
