Just an idea for a Less Friendly Game Of Chess Tavern Brawl.
- Forbidden Words - very efficient and flexible removal, use early for board control or save later for the queens
- Shadow Word: Horror - for an emergency / lategame card advanteage
- Cabal Shadow Priest and Mind Control Tech - tempo swings!
- Topsy Turvy (or Crazed Alchemist) - another swingy card, creates a very efficient clear for those low attack minions, and synergizes with the above
- King Mukla - kind of a filler, but the bananas aren't helping your opponent as much as 3 mana 5/5 on your side :)
Have fun :)
