The set and the idea are creative, but in my honest opinion, I just don't see this working at all. However, you've said you've had success with it, so obviously my theorymon would give way to your battling experiences with it.
Nevertheless, I have to wonder about the experience of those battlers that you had success against. I'll be honest, I remember facing a Bibarel one time, and I expected Super Fang right away, so there was no surprise factor. Also, Super Fang + Taunt is nice...until you Super Fang / Taunt Gengar, who LO Focus Blasts you to oblivion.
Excluding the whole "this pokemon A beats pokemon B" argument, because it is a little too specific for me, generally speaking, I don't even see much potential outside of UU.
See, at 227 speed and defenses at 352 HP with 179 for the other two, you're either going to have to bring Bibarel in on a Ghost attack, a slower Pokemon's stat upping move (rare), or after one of your Pokemon have fainted. That alone severely limits the utility of a wall breaker, as most have better immunities / resistances (Levitate or Flying / Ghost types) or have impressive Speed (Infernape). Not only that, but you really have to predict EXTREMELY efficiently with Super Fang + Taunt with how Offensive the current metagame is. Sure, you might Super Fang Lucario / Garchomp / Infernape on the switch...but can you really afford to give them that free Swords Dance / Nasty Plot? Even with only 5 turns to attack (with Life Orb), if either of those get a free one in, you're in serious trouble.
Anyway, I really like the idea behind Super Fang + Taunt, I just wish it was on a Pokemon with superior Speed or more stability. Nonetheless, this set might be viable in the UU metagame.
If only it would be explored more in-depth...
