Inital testing has been very promising for a Rings of the Brighthearth based Worker/Staff deck. It runs Rings and packs 6 maindeck Sphere of Resistance / Thorn of Amethyst. The strength of the deck is that its a turn 2 to 4 combo deck with Sphere based disruption - that is vertually immune to normal combo-hate (GY hate, chalice, and sphere based hate). And it can combo with a wide array of cards (ei: it doesn't need worker to win). However it does has a terrible issue with Null Rod.
I have a thread about the decklist in the Improvement Forum.
Also it runs 2 Volatic Keys

Take that B/R List!
