Talk:Mirror Dragon/@comment-16148116-20130821185041

As a test, I used three Oonas and one Mirror Dragon. (I had five Oonas from the last Puzzle Challenge thing as I am lame and have few active allies, so I was left with an odd-card out for a 4-7, and I prefer the higher-count evolves anyways.) I maxed all three Oonas, then Evolved two for an Oona+, then the remaining Oona with a Mirror Dragon for another Oona+

The Two-Oona Evolve resulted in an Oona+ with equal ATK/DEF scores of 6503

The Oona-Mirror Evolve resulted in an Oona+ with equal ATK/DEF scores of 6480

The difference on either is 23, which is minor in this case. It'll make a decent 6-11 evolve. Not quite as good as a true evolve, but close enough for jazz. If you're looking to fill out a missing card for limited awards, it's not a bad option -- if not an ideal one.
