I escape Kroxa, titan of death's hunger and copy it with Lithoform Engine (and have whatever that cancel out the legendary rule) - Now, do I need to sac the token, or did it escape? I'd say it didn't escape since:
702.138b A spell or permanent “escaped” if that spell or the spell that became that permanent as it resolved was cast from a graveyard with an escape ability.
Since the copy was never in the gy it can't escape. Is this correct?
A copy of a spell wasn't "cast" at all, whether from a graveyard or otherwise (C.R. 706.10), so for purposes of Kroxa and C.R. 702.138b, a copy of a spell didn't "escape", even if the original "escaped", and any permanent that the copy becomes will not have "escaped", either. (Here, Double Major is a better example than Lithoform Engine.) See also this thread and this thread.
