A Burn deck, using red direct damage spells, can potentially get a third-turn kill with Fireblast after using several 3-damage one drops (Lightning Bolt, Chain Lightning, Rift Bolt, Lava Spike), although this is rather unlikely. Fourth or fifth turn kills are quite viable for such decks. The clock slows down a bit more for players lacking certain powerful cards (Fireblast and Chain Lightning are the most probably candidates), but in multiplayer games, one might take additional damage from other players early on. A decent storm deck can outrace that pretty reliably. The best defense is a good offense. Embrace the combo, KJ.
