No, look at it this way. I am holding lightning bolts. You drop a bop...I bolt it. It dies. You drop a Dreadnought, I bolt it. It tears me a new a-hole. Same would apply if I had dark banishings. Things you might think involve bluffing really don't. Drawing out spells in the case of terrors are not bluffing. Its logical. You just have to do it. And if you had two face down creatures a bop and a nought. It would be a game of probability and not bluffing.
