Well I remember reading out a list on the show about the A Class tribes, but the rule of thumb is if it's got support like Lords, and if it's a powerful tribe that you would have used in a normal tribal game, it's probably A Class. If it takes some real thought to build, and you feel like with the right combination of other cars, you brought a normally silly tribe into something to be proud of, then it's probably B Class.
Bryan brought up a good point that we didn't really want to get into on the show in case it confused people but I think it will help in this case. He said that the B-Class tribes we talk about is more like C-Class. Tournament staples like Elves and Goblins are obviously A-Class, but tribes that aren't as organized, but still powerful like Angels and Birds can make a mean deck, and also those decks are easy to build because they have a lot of creatures to choose from and a lot of them are good. But beyond that are a class of creatures that we're really talking about - creatures like Cephalids, Crocodiles, Dryads, Dwarves, Elephants, Fish, Foxes, Frogs, Horrors, Hounds, OMG! Look how many creative choices there are. You have to add something to make them shine, because it's not always obvious.

along with the Pegasus creatures to really make a decent deck. Since pegasus are cheap to cast, I had mana left over, and when I put in the 'Tron lands, I was able to cast huge spells like
Storm Herd, and keep a
Sacred Mesa working overtime. And with that mana, you can actually use those Mirrodin Towers, like
Tower of Fortunes. Drawing 4 cards for tapping 3 Urza's lands each turn is nice, and gives you lots of Pegasuses to cast. Anyway you get the idea. Bryan's
"The Myr the Merrier" deck is an excellent example of bringing a B-Class tribe up into OMG range, where people are actually concerned when you bring it to the multipler table.
You know you are doing it right when you take a laughable creature type like
Oozes and turn it into something that makes people say oh shit he's playing the Ooze deck! Then you are a B Class Bad Ass.
