Laugh now, but wait til I rise to the Brawl elite using these tactics.
FACT: I have confirmed that not only is it impossible up-B out of the Friend-Cancel, but you are never actually able to up-B again.
Believe me. I am a top-level pro in Strikers and Medal of Honor, which maybe 1000 people play...combined. Ignore the fact that there are not only smash pros here, but probably Halo, Counterstrike, Street Fighter, and other games that have millions of players as well.
I can't even beat my small group of friends with these tactics...YET! In fact I'm the worst out of 60, but just wait, you'll see.
