Lets say, I have a noncreature artifact (Manalith for example) and something, which temporarily turns it into creature, like Karn, the Great Creator's +1 ability. So I have a 3/3 Manalith and I cast Clone copying the Manalith.
From the rulings for Clone:
Clone copies exactly what was printed on the original creature and nothing more (unless that creature is copying something else or is a token; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras attached to it, or any non-copy effects that have changed its power, toughness, types, color, or so on.
Does this mean, that I get a plain Manalith? Or do I get a Manalith creature, which dies, because Manalith doesn't have any power or toughness? Or something different?
(I am asking this question, because once a long time ago, I heard a judge talking about some kind of an interaction like this making the clone/copy die, but I am not sure what cards it involved (or even if there actually is such an interaction))

syntax here which saves you getting Gatherer links yourself, I'll edit that in.
