Me, I'm a mage, I love all the great spells and spell synergy minions there are.
Currently I'm focusing on a buff deck, minions that are either buffed by spells being cast, summoned from spells being cast or cheapen spell casts, and some others that are just fun. It works great so far.
This is what the deck looks like. If I manage to get out both my Mirror Image then the Cultist Leader and my opponent has to kill the Mirror Images, good times. If I get the Ghoul out and my Mogu'shan, I can hope for the buffers to buff them up, and then the 2 healers to keep them up. The Ghoul profits from the Mirror Image deaths just like the Cultist Leader does. Or if I get most of my spells I can destroy any minions my opponent puts out, or survive long enough to get 1 or both Flamestrikes out. If 1 or both Apprentices survive I can even do such expensive spells 1-2 rounds earlier. If I manage to get my Violet Teacher up for when I'm gonna cast these spells, and THEN put out the buffers, oh man!
So far, it's worked in all those situations.
So, what's your class and deck? How does it play?
