Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
You do not list all possible moves in the actual sets. CB?! you mention it in Optional changes. and there are no tiers yet in 5th gen, apart from ubers.
Yes, but Porygon-Z lacks the power to muscle its way through those walls (namely Evo-Stoned Chansey or Blissey). Although it does have only one weakness (fighting), FIghting is extremely common nowadays *cough* Roopushin *cough*. ALso, it lacks resistances.
Magmortar isn't actually [i]that[/b] bad. It has few saving graces over Heatran, namely higher Speed, Cross Chop as a way to deal with Blissey (as opposed to Explosion on Heatran) and Thunderbolt.
I agree with SOMALIA. The Choice sets are pretty bad but the Mixed Wallbreaker is actually pretty...
your calcs are kind of weird. not saying that they're wrong, but seriously? Chansey isn't staying in on Nidoking in fear of Superpower. Sucker Punch usually won't hit because Claydol is going to be screening/SRing or whatever. And Muk?! Muk!? Also, being locked into Focus Punch or Sucker Punch...
