EuroGamer - Pick a card, any card, and I can probably tell you what it does. Backstab? One of the rogue's finest - zero mana cost, does two damage to an undamaged minion, useful if you can buff spell damage beforehand. Knife Juggler? Love that card! 3/2, which is great value for two mana, and he tosses a knife at a random enemy every time you play a minion. Always in my deck. Ragnaros? By the time you see it, you're dead already.
