All Celestial Mages have 4 super attacks, but is not any Celestial Mage who has A LOT OF MAGICAL POWER like Lucy.

Summon The Key 13 (Lucy has not this one key); Urano Metria; Invocation of the Spirit King; Summon three spirits at once

Lucy used three spirits at once, Invocation of the Urano Metria WITHOUT GEMINIS (I guess) and she summoned the Spirit King. She can't use the Key 13. What Lucy did is dangerous to her health because she used a lot of magical power. So I think Lucy goes win

If the Spirit King lose will happen it: http://fairytailcouples.wikia.com/wiki/File:Opening_15_04.gif
