I hit rank 13 last month with a non-dragon Reno Priest. i mean, it had SOME dragons in it (Azure Drake, e.g.) but it wasn't a "dragon" playstyle. It was a control deck designed to outlast. It was super topheavy and full of taunts and heals. It worked great against pirate warrior but almost always lost to Jade Druid. Worked fine against Jade Shaman.
I hit 500 wins with it and am now so sick of priest I don't ever want to play priest again, so I deleted the deck.
