I disagree with most of Fawe's post except for the Doomsayer, Molten and Unstable Ghoul. At worst, Doom an early one turn stall tactic. It also has uses in the late game and you have limited removal options as a Reno deck. Unstable was only great in the ridiculous Patron deck. Dropping a Molten for free can sometimes just break other decks. Nothing(NOTHING), is more satisfying than dropping a Molten, Reno, and then Y. Brewmaster. Of course you have other ways to get multiple Reno's but you get the point. Have you thought of Refreshment Vendor? It can work with those duplicates fairly quickly to get you back in the game at times. It also has nice toughness.So here is my current Reno mage project. I'm basically undefeated against other control decks, this deck is completely unstoppable if I manage to drag it out into the late game as I completely bury my opponent in card advantage. I just haven't figured out how to shore up the early game, which means the deck is weak to the most common stuff on the ladder like secret pally, face hunter, and aggro druid.
Mage - Deckbuilder - HearthPwn
Incidentally, Ethereal Conjurer is a total mvp in control matchups and a high priority for duplicate. If I were running control mage without Reno he would most likely be a two-of.
Fawe's choices fit Reno Lock to a T but I'm not sure they are superior options for mage.
Edit- on another note, I want to like Reno mage but the card draw of Lock is just hard to ignore. I like the early game options better too. Reno mage is a better Reno deck head to head though.
