Flyer. This dragon breathes a toxic gas at the beginning of the battle, preventing an opposing champion from using spells, unarmed combat cards, and blood abilities.

The special power only stops the opposing champion from playing any spells, unarmed combat cards and blood abilities into battle against Greyhawk Dragon. These cards are not discarded by the Greyhawk Dragon, they are just treated as if they didn't exist. Good examples of this would be Find Familiar [FR-40] and Battlewise [BR-37].
There are rumors along the Savage Coast of a wandering dragon sage, moving from village to village in that war torn land. Some believe this creature to be a mighty spellcaster or adviser to some lord in the Pomarj or possibly both. Whatever the case, it does not bode well for the folk that live there.
