Not if they are using Econ, Etaqua, Floodgate etc... I used a first version of my deck with 3 Impenetrable Attack and WoD. I stopped doing that after playing against a Mirage Dragon deck :D
I know it is powerful but most of GB player use imp attack which cannot be activated when mirage dragon is on the field with econ ... superrush headlong , floodgate etc.... that is the point i am talking about and if they use halfshut so superrush headlong welcomes U xD
