Lax set is interesting. However, its lack of Rest brings up the next point, which is...
...that the lack of fallback isn't. You're basically forced to just surprise the opponent with first-turn Exploders and hope you catch the right stuff, because you have a lot of issues with very common things that either force you to explode defensively and predictably or just flatout beat you. Curselax, Zapdos, Vap, and the odd ML Pass Umbreon all wreck you if you give your opponent time to catch on.
Rock Slide and Roar on Ttar helps with most of this (except for Vap, obviously), I mean RS > Dpunch because of what Borat said about Zapdos and Roar > Fire Blast because the Fire move is not really doing too much for you unless you're trying to sweep with Ttar (which really isn't happening).
Also, while it makes this team look a lot more "standard" and doesn't synergize quite as well on offense, Zapdos over Muk or Pgon2 would help - it's hard to fully explain everything Zapdos does for you, it's just Zapdos, it just works. And yes I'm really suggesting Zapdos like this.
For a surprise this team works well enough (though really at the very least put Rock Slide on Ttar). And ultimately, that's probably what you're looking for with this team. However, a lot of your descriptions assume you have more time to play around with your opponent than you usually will. The more you try that slower stuff instead of just Exploding, the more time you give people to realize what you're up to or to build up momentum of their own. If you want the time to do what you say you can and not just Explode like a madman, you will need more fallbacks and better defensive synergy (i.e. a more "standard" team).
