The amount of satisfaction that I get for correctly guessing a card in the opponents hand is also something that a lot of cards dont offer in Cube, with Cabal Therapy and Meddling Mage being much, much weaker in singleton environments
Without having to resort to any narrow cards or other tribal elves you can have a very potent Priest of Titania indeed
