This is a great deck for those times that you just want to mess with the opponent's head and screw up and and all game plans he may have.
Looks for an early game Wyrm or Kabal (and a secret). Use frostbolts to control the early game and keep board control.
Aim to get a Counterspell and/or Spellbinder up for the Ethereal Arcanist to get it protected - and ideally a clear to minimal enemy board to keep it upright.
Then look to start duplicating up with the Faceless.
If the opponent is almost down but has cleared your board or blocked you, use the Fireballs to finish him off.
Have fun! :-)
