I'd suggest you to try out Potion of Illusion  with one Conjure Mana Biscuit and/or Leyline Manipulator. You can create 1 mana version of Coldarra Drake that you can drop down to 0 and with Mana Biscuit you can threaten with a lot of damage. If you build rest of the deck to provide pressure/ stave off early game, you might not even need full 36 damage potential.

There is so much more to Potion of Illusion beyond this. Getting additional copies of Medics, Reckless Apprentices, Fallen Heros. Setting up very cheap Potion of Illusion by first dropping it on Kalecgos and so on.
