I am sure, if possible, I'll receive negative rep from all the Ghostmare haters

SNovas = qaunta for everything, helps Ghosts, and SoFos
Discord = three to hopefully get one somewhat early
QuickSand = for obvious reasons
SoFo = shields, weapons, lones pillars and then the beautiful Black holes
Games are slower but usually not much from the opponent.
If you want it to be 30 cards, you could take out a SoFo, Quicksand, (or Supernova--though not recommended.)
Not really tested anywhere, I'm sure it does well in Ai3, probably bronze maybe Silver.
Have fun
