I like the mechanism of limiting DEF of Beast and Wretch by number of cards in control hand.
Knowledge of Eternity probably will be must have due to positive flip for initiative - Activating Tara first and using Temporal Shift (discarding whole hand) can be great advantage when Beast and Wretch has DEF reaching beyond the scale of models in Open Beta.
Of course no cards in Controll Hand is quite dangerous ...
