/**
* Cloning a face-down creature should produce a plain 2/2 creature #3582
*
* What I expected: Using a clone effect on a face-down creature should
* create another 2/2 creature.
*
* What I observed: The resulting token appears face-up as a copy of the
* face-down creature's front face, copying its power/toughness but not
* abilities.
*
* To reproduce: Play a Terastodon, then an Ixidron. Terastodon is turned
* face-down. Then play a clone creature (such as Progenitor Mimic). It
* appears as a face-up 9/9 Terastodon token, but without any ETB triggers.
* The next turn, when it copies itself, it creates a Terastodon that does
* have its ETB ability.
*
* https://blogs.magicjudges.org/articles/2014/09/16/morph-rules-problems-face-down-in-a-face-up-world/
* explains that cloning a face-down 2/2 creature should create another 2/2
* creature with no abilities (see Face-down Creatures and Clone).
