After editing the deck I realized it is NOT extended legal. You must remove the 3 sol rings. I suggest adding another contagion clasp, ichor rats, and necropede. You can further"demodify" it by removing a tezzeret, a karn, and the 2 skeleton shards in order to add 1 treasure mage, 1 ichor rats, 1 more everflowing chalice, and 1 core prowler. That is a very slow yet safer modification that relies even more so on the proliferation aspect. It's more likely you will need to -4 Tezzeret with this set up. It's not "Legal" but taking out four swamps and islands for their artifact equivalents gives you an extra boost for artifact and/or land draw. Finnally Virulent Wound, and Grim Affliction help continue the same thing through differant means. Conversely the use of spells like Turn Aside and Steel Sabatoge can save all of your permanants and let you recast the ones with upon entering the battlefield effects.
