I have made Rank 5 with Raptor Rogue in the past, without much issue in fact.
It's a straight forward minion tempo deck. Sometimes you get god curve with Nerubian Egg into Raptor then steam roll out of control. I run Cold Blood and Defender of Argus for Egg activators. Curve goes: One drop (Leper Gnome or Clockwork Gnome), Nerubian Egg/Haunted Creeper, SI7/Harvest Golem, Shredder, Belcher, Sylvanas/Piloted Sky Golem, Dr Balanced. The rest is the usual Rogue staples like Backstab, Eviscerate, SI7 I also have Dark Iron Skulkers in there for the clutch board control.

This is what I use only I don't use Fan of Knives I use Dark Iron Skulkers and I use 1 drops instead of Loot Hoarders.
