Also, this is not a mono.
tbh, I think that this is a lot slower than other Lava Destroyer rushes. And the RoL's just mess with the mulligan, ensuring that you either get no towers, all towers and 1 cremate, or all towers and RoLs. Better option is to take Brimstone Eaters, as they pay for themselves the turn after you play them. And they help out with the damage; double that of RoL. Then it would be mono.
