This is a degenerate combo deck that is capable of winning the game as early as the first turn. It does so by putting Griselbrand into play and then drawing piles of cards. Thanks to Nourishing Shoal along with Worldspine Wurm, we can often draw our entire deck. This lets us use our fast mana to put Borborygmos Enraged into play as well to kill our opponent by discarding lands. You can find some sideboarding notes for those archetype here.
