My opinion on sludge belcher might be changing. It's ubiquitous on the ladder...
I think its popularity is higher than it should be, meaning it is overrated as good of a card it is.
I think spectral knight and azure drake are equally viable 5 drops and you generally can't fit all of them.
I think once the game slows down I'll bust out my slow aggro rogue deck that runs anubar ambusher. I freaking loved that deck the week or two before hunter became super popular. 5 attack ensures belcher is not an obstacle, plus it doesn't usually hurt me because people are hesitant to send back an si7 agent or azure drake due to the on play benefits so they generally kill my board so I don't get the stuff back.
I think it is a great deck vs control because I can play slow, feed into their card draw, and then slam coldlight oracle and sap-kill targets and then explode with burst combos like loatheb + coldblood.
Only problem is, I have to remember what was in that list... lol. I'll probably make tweaks like removing backstabs since it does appear that the meta is moving away from aggro anyway.
