What you want to do with this deck is use the Merfolk Looters to get to the cards that will win the game for you. Since you have to be drawing and discarding a lot there are cards that will do you good if you have them in your graveyard. All of the counterspell, boomerang, and other control cards are there to help stall all of the madness decks until you get to the cards that are protected, giving you a major edge. City of Brass helps you if you don't draw the right land cards, and since they produce any kind of land there are a couple of cards that require a forest to play and can help you in a tight spot. I have a green side deck since there is some green in the deck already with cards such as Ivy Elemental and other strong green cards.
