I think deathrattle rogue has potential down the line, but there are not enough deathrattles to make a cohesive deck that relies on their synergy cards atm. I think burgle rogue might have potential though, especially alongside the secret package.
Does anyone know how the interaction between Sketchy Information and Korrak Bloodrager works? Cause if Sketchy Information summons Korrak that could make a big difference for the deathrattle rogue archetype. especially with the card that doubles deathrattles for three turns, that would make a crazy board of Korraks. Korrak makes this deck spicy. just not sure if it's spicy enough to be viable
