For the past few weeks I've been trying to splash the new unchained cards in other fiend decks, but this is the only one that isn't a bricky mess.
The theory is that you can use Ariane to summon Arianna to search whatever labrynth piece you are missing and then link into the new unchained link two. From there you can search the new red soul, or if you opened that you could get the big guy. You then pop a backrow to summon the red soul, then link into rage so that you can make unicorn on your opponent's turn.
This deck probably isn't good as I don't think labrynth needs the extra disruptions that this engine provides, and while I said this deck isn't a bricky mess it's still not consistent by any means.
Floodgates are for nerds so I refuse to play them. (If you get the irony of that then congrats you get an imaginary cookie)
