Mulligans
Dead Ringer Basically at a later stage when there is not much cards left in oponents deck you want to play Hakkar via Coffin Crasher and/or Reckless Experimenter then if you want it can be doubled or trippled the next or same turn with Shadowy Figure and lastly you play Elysiana to get rid of the bloods in your deck and get some discover avesomeness :D!
As for the rest of the deck it has to be adjusted to keep you alive as long as possible. The cards can be swapped. Im not sure about omega medic tho
