This deck runs a lot of "Jester's Cap" type effects.
Top card of library revealed / Look at top of opponent's library (to know when to exile the top card with my general)
Buyback spells and cards that return to hand (for general)
This is a fun deck to play, and is pretty good against combo decks that tutor for their win conditions.
