No.
Only
creature could use their skill twice during this turn. Non
creature only got the cost reduced to 0. They can't use the skill twice nor could they use it this turn.
PU could work. Probably. Needs more testing.
EDIT: wait, i didn't see Sev's post in the next page. Sorry.
EDIT2: after a few testing, i figured this out:
-SoR, +TU
Pros:
One less rare.
Against god without CC, you can go Dragon -> Mito -> SoR -> TU to double your dragon multiplication. You may even shave a few SoR or two this way.
Less chance to eat
or
Cons:
With any FGs with DR shield, you have to use Chimera. (which significantly increases the number of Gods which need Chimera)
More unstable because of the above reason, particularly if you didn't draw all your SNs before you get all cards you need.
