If you counter, you basically lose. Because your opponent has, a hypothetical 11 win cons, 4 street Wraith, and 45 acceleration, so that there's little to no chance that he's holding at least two more win conditions, which is what you would need to have your counter be effectful. Otherwise, he ramps up to that 4 mana through your counters and plays what he was gonna play anyway. 8/11 of the time. Or, he could cast Burning Wish, and find something good anyway.
