The goal of manaless Ichorid is to Draw, Discard, then Dredge, using your natural discard as your discard outlet. These points are so important that I would also only advise to mulligan is if you don't have a dredger.

This variant of the deck will always choose to be on the draw over the play(to have 8 cards on turn one and naturally discard), And you should also always have a dredger in your hand. Manaless Ichorid Nicholas Rausch's 1st place SCG Cincinatti (228 Players) This variant increases speed, consistency and reliability of tradional dedge at the cost of losing fate out against a turn zero leyline of the void. Manaless Ichorid in legacy did not begin to take root as a serious archetype until the following list placed. Over a few turns creatures like Narcomoeba and Ichorid came onto the battlefield and are sacrificed to either wreck your opponents hand with Cabal Therapy, or put a game winning creature out with Dread Return all the while making Zombies with Bridge From Below. The deck worked by using the dredge mechanic to grow it's grave yard. The mechanic did not gain an archetype of its own until one block later when dread return was printed in time spiral. The first card featuring dredge to be seen as playable was Life From the Loam and was used in decks like Confinement Aggro Loam and Enchantress. The Dredge mechanic was first printed during the ravnica block on green and black cards and was origonaly considered to be a junk ability. Many people will have no Idea what's happening when you're playing it and often it will feel like you're playing alone. It wants it's opponent's creatures to live, it's creatures to die, it's deck to go in the graveyard and it wants not to draw cards. People sometimes call Ichorid the 'crazy backwards upside down deck'.
