You wanted feedback? Fine
Don't expect it to be anything more than a point by point summary though, too busy for anything more ATM. I'll just mention the things that stood out to me after another quick glance.
1) Centaur Charger:
-Centaur + Mounted Combat doesn't work, you know that. So a lot of this build is based on a false assumption.
-An 'Orcish Centaur'? Really? Now where would the rules for that be? The only thing that comes to mind is the Tauric Template. Centaurs are a race, not a templated creature.
-As for the 1-HD Lycanthrope, that 1 HD DOES add to ECL, nowhere in the Lycanthrope entry is it mentioned that a 1 HD Lycanthrope can replace his animal HD with class levels. Further more they are treated much like the character MULTICLASSED, so not as racial HD, and they are never the creature's first HD, unlike racial HD.
-Swarm Favored Enemy, another house-rule.
-Custom Bloodline, I guess you needed to make up even more stuff to make it work.
-The character isn't completed until well into Epic level, while normal CO/TO builds are generally made within the course of 20 levels.
-You think something ToB is overpowered? Really? After extensive houseruling to come up with a simple charger you deem something that might prevent it from acting first as overpowered? God forbid you face a character with Celerity, or just a damn good Initiative score...
-Girallon's Blessing and Girallon Arms don't increase the base damage of your natural weapons.
2) CoDzilla
-What are you going to Persist? Level 1 spells? How is this guy a useful contribution to the party?
-You explicitely need an expensive item to make the Wild Shape abilities of the build function.
-Trappings of the Beast Item Combo only advance the Wild Shape Class Feature.
--> MoMF doesn't grant Wild Shape, it just stacks with existing Wild Shape for purposes of max. HD and duration. So you won't gain any extra MoMF forms or abilities by using items.
--> It's very debatable to actually call Wild Shape granted by an Item a Class Feature, so a lot of the Wild Shaping hinges on DM fiat.
-You're talking about using a Custom Miracle Item. Well, in that case I'm sure you don't mind everyone goes Wish-farming, right?
-Requires a Deck of Many things, and a custom variant as well. How you gonna prevent the deck from handing you crappy cards? Need more custom items for that?
3) Sneak Attack:
-Deadly Precision weapon enhancement is +1d6, not +2d6
-Martial Stance feat needs to be taken twice if you want Assassin's Stance, since you can only pick a first level stance as your first stance.
-How do you intend to hit with such a crappy BAB?
4) Halfling Mount
-There is no ECL given for Dragons, so it's impossibleto determine the level of your Cohort mount, assuming this build even functions properly, which it doesn't.
-Dragons only grow to Colossal plus, no larger.
-The base character pretty much sucks, you'd be playing a mount with some excess baggage tagging along.
-The Waveriders mount class ability is explicitely called Waverider Mount, that is something completely different from Special Mount, which means it doesn't qualify for a lot of the feats and class abilities you use to increase your mounts HD.
-The use of a Dragon as a Special Mount is explicitely stated to be only useable by Paladins, your build doesn't get a Special Mount as a Paladin.
-The table for Dragon mounts only goes up to Young Gold Dragons, there is nothing mentioned about Great Wyrm Colossal plus size Gold Dragons.
5) Triple 9
-Been done to death, and in more elegant ways to boot.
-Your build requires an expensive Magical Item, again, and at a relatively early level.
-The use of Reincarnate. The result is completely random, and a Beholder is not listed as one of the options. Your only hope here would be to roll that 100 and DM fiat/fellatio.
6) Eldrith Blast
-Waddayaknow, it actually works as advertised, that's a first
-Been done to death, and with 9th level spells too boot, don't try to sell it as your own exclusive discovery, or any of this stuff for that matter.
-Before you call something a world record, first check the actual world record, and make sure your stuff actually follows the rules, like any other CO-build.
That's about it for now, hope you're happy I took the time to point out the obvious.
