Since I got Thalnos, I decided to give this Miracle Rogue a try. I don't have the Preparations or Leeroy, but I replaced with the not as good Arcane Golem and put some minions in instead. I also found that if those minions were Preparations, I probably wouldn't have enough things to keep board control in the early game.
I found a couple different peopel online who wrote about their Rogue decks and I sort of mashed some of each together. Some went more spells, some had a couple more minions. For instance one person put Acolyte of Pain in for extra draw which I think isn't bad. Personally I put in an Earthen Ring Farseer because I found that I often was taking quite a beating before getting to play my Gadgetzan Auctioneers. I also have two Conceals while I found some decks only put in 1 conceal. I thought there also could be an arguement for Perdition's Blade, but I didn't end up putting one in. I also don't have Edwin Van Cleef so I put in a Questing Adventurer, which although mostly not as good, you can play it first and if it lives it'll still grow as opposed to Edwin who won't.
Anyone else here have good tips for Rogue decks?
