This deck quickly fills its graveyard with creatures to fuel big life gains and even bigger threats. If the game stalls, it can use Laboratory Maniac to win instantly. It's an extremely fun deck to play at the kitchen table, it's pretty cheap and challenging to play optimally. It's also very effective and almost unstoppable without graveyard hate.

All Stars:

Gnaw to the Bone is an innocuously powerful card in this deck. With a graveyard full of creatures, a single cast can gain 40+ life at instant speed. It allows the deck to spend its early turns dumping creatures into the graveyard with Magus of the Bazaar, Tracker's Instincts , or Hedron Crab and then stabilize with a big life gain and start dropping threats. This deck couldn't exist without it.

Spider Spawning generates a huge wall of blockers that can stall the game until Laboratory Maniac steals the win. I've had opponents scoop in response to this resolving, and being paired with Gnaw to the Bone gives this deck a very potent defense.

Kessig Cagebreakers is the big finisher. I love slamming him down while sitting on 70+ life and a over twenty 1/2 spiders with reach. Opponents usually have no way to block the wolves and Genesis is there to bring him back turn after turn.

Genesis has a key role in this deck: it will inevitably get milled and allow you to return one creature to your hand every upkeep. This means the deck can continue dredging Life from the Loam without losing board presence. It's also the main way to make Kessig Cagebreakers happen every game, and if the deck runs out of library, it will bring back Laboratory Maniac for the win.

Self-Mill:

Life from the Loam is the main way this deck fills the 'yard. Once one gets milled, dredge it at every opportunity. It will generate insane card advantage, allow the cycling lands to be recycled, and fill the grave with more creatures and flashback spells. It does everything this deck wants to do.

Tracker's Instincts is a great card to have in your opening hand. It can also flashback if the deck runs out of steam milling itself, and dig for/power up Gnaw to the Bone in a pinch.

Hedron Crab is a creature that can mill a lot of cards, which practically makes it an auto-include in this deck. When you consider that this deck plays a land every turn thanks to Life from the Loam, Hedron Crab becomes an extremely efficient way to mill. I have never used Genesis to return one, but if you find this crab in your opening hand, it's golden.

Magus of the Bazaar is at first glance a junk rare, until you see it played in dredge, where it's the poor man's Bazaar of Bahgdad. In this deck, however, what matters is the number of creatures in the grave, and that makes Magus of the Bazaar better than its forbearer. If it does hit the battlefield, this Magus allows the deck to dredge multiple times a turn and discard unwanted cards like Genesis, Wonder, and Golgari Grave-Troll. It's deceivingly powerful.

Golgari Grave-Troll is played as a one-of for its high dredge cost. It has saved my butt on a number of occasions, because it digs so deep, allowing me to hit a much-needed Gnaw to the Bone . This deck especially loves to dredge it using a Magus of the Bazaar or a Cephalid Coliseum only to discard it again. I've listed this as a self-mill card because that's what it is; it should not be played for its body, leave that to Boneyard Wurm and Splinterfright .

Threats:

Boneyard Wurm is incredibly undercosted in this deck. It quickly gets bigger than Ghoultree and can be very dangerous with a Wonder or Brawn in the grave.

Splinterfright is the biggest threat in the deck. It shares a P/T with Boneyard Wurm , it has trample and it helps mill your library, all things that this deck loves. Unless your opponent can deal with Splinterfright , it can quickly take over the game.

Ghoultree being locked in at 10/10 gives this card limited potential compared to Boneyard Wurm and Splinterfright , but playing it for one mana is a fair trade off. You will learn to love seeing these in your opening hand.

Evasion:

Wonder is a nice fit for the deck. It's a creature, so it contributes to Gnaw to the Bone /Spider Spawning and the P/T of creatures like Boneyard Wurm , plus it provides an extra level of evasion for all of this deck's creatures.

Brawn is the icing on Wonder's cake. It ensures that you can attack through nearly any blocker, and it's a creature to boot. It fits the deck nicely.

Utility Lands:

Lonely Sandbar& Tranquil Thicket are both excellent ways to dredge and Life from the Loam will return allow these to be used again and again. These lands are also useful as an uncounterable way to draw a card when Laboratory Maniac hits the board.

Alchemist's Refuge allows the deck to play Laboratory Maniac on the upkeep before drawing out. Though this does require a greater mana commitment, the hope is that deck is prepared for the cost by then.

Cephalid Coliseum, when paired with Life from the Loam, becomes an incredible card advantage engine. This is particularly true here, where discarding cards doesn't prevent you from using them. When you're ready, Cephalid Coliseum can also kick dredge up to ludicrous speeds, as each draw trigger can be used to dredge.

Dakmor Salvage provides the deck with additional dredge targets and will ensure that it can pay the flashback cost of Spider Spawning. Think of these as mini version of Life from the Loam, they make sure you hit your lands while setting up for the true dredge engine.

Dryad Arbor simply increases the creature count without impacting the mana base. They are slow and can die to removal, but the idea is to mill them.

Alternate Win:

Laboratory Maniac should be a last resort for this deck. There's nothing worse than playing this guy at the last second only to have him removed instantly. For this reason, the deck wants to back him up with Cephalid Coliseum or the cycling lands to respond with instant draws of its own.
