My point is that just because you drew Brainstorm doesn't mean you instantly won. SotF did this, Flash did this, Mystical Tutor arguably did this, Brainstorm does not do this. It's power level is not comparable to cards that have been banned because of how game breaking they are.
No, it's not an OMG I WIN NOW! (excluding some combo scenarios) card. Brainstorm decreases variance and it's most evident in the long run. If you played Brainstorm for 10+ rounds you're allowed to say, OMG I WON MORE OFTEN THAN EXPECTED!
