If the basis of this deck is poison with dune scorpion and then sit behind a dissipation field until they run out of hp I would make a few revisions to make it run more stable.
1st I would remove the nymph's tears, Chaos Power, and Blessing and add 2 moore Dune Scorpions so You have a higher chance of drawing them early.
Since you are using dissipation field, replacing the supernovas with quantum towers may be a long term good idea. This wil also allow you change to the time mark to better power your time centered deck. Although discord an lobotomizer are great weapons, an eternity has the best synergy with a dune scorpion based strategy so I would swap them.
I would also think that 2 dissipation fields is too few to ensure drawing one on time. You may want to reevaluate your shield situation to make sure you are always covered since you have no healing.
