did you lose to the time mark elder? I would imagine his reverse times would have been very frustrating for you
Against decks that I know have RW or Eternity, I will hold my buffs until I can duplicate it a couple times. I really only need two or three to beat them down effectively. Or I'll play the Deja Vus without buffs and wait for the AI to waste RWs on them first, then buff them later.
