Probably a mistake from the editor. The correct card would be Invoked Magellanica or Invoked Caliga or even Elemental HERO The Shining or Escuridao to use with Miracle Fusion.
It doesn't appear to be a mistake as it's just added to take the 6th slot. As you can see, there are 3 fusion cards which would be used to summon E Brave Neos. Even decks in the street replay have cards in their EX Deck just for show
This isn't the first deck i seen posted with a card being there for show. A few months back there was another card there. It might have been a custom deck with Neos Fusion first debut and they were trying to cram Neos into everything
