Extra Deck:
-Staple Stuff, you can add Armor Master and Dark End Dragon. Thought Ruler Archfiend is also a good choice.

Thoughts:
I played this deck against Six Sams and won 9-3. This deck as a lot of consistency, loves to remove stuff from play and is playable against a lot of the meta. Usually giving you the first game easy.

Consistency out the ass, Alchemist recycle Faders, Faders help Caius or E-Con, Tomato can search for a lot of things, including Krebons that stops OTK like a boss, Sangan searches for about everything, Maxx "C" is a boss, need I say more? go test it out for yourselves.

Hand presence: Veiler, Fader, Maxx "C", Gorz, Honest. Giving you variety depending on what your opponent does, and all of them are very good cards that deserve their place in the deck.

Field presence: Lots of floaters, giving you easy tributes for Caius or E-Con, nobody likes leaving a Chaos Sorcerer on the field, and will have to deal with it.

Chaos Sorcerer is a lvl6 Dark Monster. After using his effect it is quite easy to simply summon Krebons or Plaguespreader to Sync for a lvl8.

Mind Control, even though we only run 3 tuners, is there because it is just too easy to get those tuners out. Sangan, Tomato, searches for everything you need.

This is a control deck, so do not think about making a huge push without killing your opponent because chances are, you will lose against his counter-push.

What I would change:
Not much, the 2 Dimensional Prisons can be replaced by BTH. Perhaps finding some space for Forbidden Lance to give weaker monsters a chance to tackle bigger ones.

First, this Deck is just good. Some minor fixes:

-1 Ryko, Lightsworn Hunter (Too random at 1, you need to add 2 or 3 to be effective)
-1 Krebons (Just not as good as with E-Tele)
-2 Mystic Tomato (Don't like it here, just not enough target for it)
-1 Plaguespreader Zombie (Without milling, I won't add this to the Deck)

+1/2 Breaker, the Magical Warrior (just too good and too Stun to not add it here)
+2/1 D.D. Warrior Lady (c'mon, how could you forgot it?)
+1 Neo Spacian Grand Mole (good stunning card, and good anti-Synchro)
+1 Rai-Oh/Cyber Dragon/Battle Fader/Spirit Reaper/what you want

I would also drop the 2 Enemy Controller for 2 CED or 2 Smashing Ground, but it's your choice.

Mystic Tomato targets:
-Mystic Tomato
-Krebons
-Sangan
-Gale
-Plaguespreader
-Spirit Reaper

So I've got tons of targets for a lot of different situations. Plague is actually good in hand with Chaos Sorcerer (Spc Summon Chaos, remove something, summon plague and Sync for lvl8). Krebons stops OTK like a boss, and is a lvl2 Tuner (Works great with Chaos, like Plague)

You don't want to mill too much with this deck, which is why one Ryko is enough. Lady could take it's place though, but since Ryko can hit backrows and can mill targets for Chaos.... Hm I'll think about it.

E-Con helps replace Book since you have a ton of targets for it anyway.

Lastly, I didn't catch if by "this deck is just good" you meant that it was only good or amazing
