Yeah -- keep the concept, but reduce the card count.
Try, for example:
52g 52g 52g 52g 52g 52g 52g 52g 52g 52l 52l 52n 52n 52n 52p 52p 52s 52s 52s 5bs 5bs 5bs 5bs 5bs 5cg 5cg 5up 5up 5uq 5uq
Mark of Darkness
2x Steal
2x Nightfall
5x Emerald Pillar
2x Green Nymph
9x Bone Pillar
3x Graveyard
3x Aflatoxin
2x Plague
2x Skull Shield
That will give you a much better chance of getting your combo together. Aflatoxin to elminate a big critter and start generating Cells, Nymph to make those cells go berserk filling up the enemy field, Skull Shield so they don't kill you along the way -- then Graveyard+Nightfall+Plague for a mass of 2/2 skellies waiting to be Adrenalined for the kill.
It's pretty vulnerable to permanent control, but it's pretty nasty if the opponent doesn't have any.
Good luck!
