Ignoring the quanta imbalance, it looks very weak to Creature Control, and the with main offensive point of the deck as poison (medium/slow speed for a fully offensive deck) and no CC of it's own or defensive cards it will be fairly weak in t50. Having said that I do love two things about this deck:
Firstly, It has Physalias in it!
and secondly, there is no vital need for Permanent control.
