Ravnica/Time Spiral standard was weird.  For one thing, there wasn't a prototypical aggro deck in the format.  For another, the format produced an oddball like this.  Brine Elemental was the namesake of the deck, and when combined with Vesuvan Shapeshifter, it led to one of the last true prison endgames.  From the minds of Paul Cheon and LSV, it's Pickles!
