No comments on my Monmen? lol way to read the OP
Umm I'm not familiar with Ubers so can't comment much on the Dialga.
From what I can see that Ranculus is walled easily by Dark or Steel types and is also extremely vulnerable to phazing. Since you are boosting your defenses, you may actually want to invest more in SpA so you can hit Steels harder. Since Blissey is beaten by Toxic Spikes you may even want to replace Psycho Shock with a different move with no immunities.
