This deck tries to maximize your chances to play 4 cards with the same name…and consequently to complete your quest.
Cards used to maximize casting of a card:
Shadowstep , Gadgetzan Ferryman , Youthful Brewmaster, Mimic Pod and Shadowcaster. Use Coldlight Oracle, Mimic Pod, Fan of Knives and Vanish to draw the necessary cards quickly.
My favorite re-cast target is Stonetusk Boar but most of them are ok due to low mana requirements.
Once your quest has been completed, play Imp Master, Hogger, Violet Teacher, Illidan Stormrage and Moroes to spawn extra 5/5 after every turn. You fill your entire board with 5/5 minions super quick that way.
The deck is a bit weak early on, but tends to turn into a monster after turn 5 and 6.
You can use a 2nd Violet Teacher if you don’t have Illidan 😉
