I believe that the main downside to
Stromkirk Noble is not that it's a horrible top-deck (and that by itself is pretty bad already), but that it's best possible scenario, which is being cast on the first turn, is very underwhelming. It deals only 1 damage on turn two, and that is given that your opponent simply allowed you to get him through. It will be able to do a total of 3 damage by turn 3, given that you've had two uncontested attacks. Consider that, by comparison,
Spark Elemental also costs 1-mana, but is able to deal 3 damage in only 1 turn, and also has Trample (which makes
Stromkirk Noble's evasion pale in comparison) - and even then
Spark Elemental has never been an auto-include in Burn decks! :laugh:
