Revisiting a deck I've covered before today because I've become more familiar with how the builds should work. Back to the Sangan search deck further down the page, although the build shown there is now vastly inferior to my new versions.

1 Dark Hole
1 Heavy Storm
1 Mind Control
1 Monster Reborn
1 Mystical Space Typhoon

This is the frame that makes up the basis of the deck. The remaining space in the deck can be occupied by an engine of the player's choice, provided there is space.
Black Luster Soldier is now in there because of the easy searchability of Effect Veiler. You'll often add it to your hand, and usually get some use out of it, so drawing into BLS can be devastating.
Gorz is now in there over Fader because Fader wasn't proving useful enough. Gorz might not be searchable, but like BLS, it wins games when it's played.
Reinforcement of the Army is a recent addition because it deckthins and searches an Armageddon Knight, which is nearly always a good thing if you have stuff left to send to the graveyard.
Veiler and Maxx "C" are there at 3 and 2 respectively to remove the need for Solemns. It might sound like a poor replacement at first, but they are all searchable, they are hard to predict unless the opponent saw you add them, and they cannot be hit by backrow destruction. This has the pleasant bonus of making every backrow a chainable card and a +1 if the opponent hits it while you have Sangan in the graveyard.
Of the spells, if you absolutely have to take something out, Mystical Space Typhoon is the best choice. Make sure to side as many as you can though, Macro is a painful match-up.
The extra deck is just general staples. Stardust is not a staple in this, and I don't run it most of the time because there are just better options. Level 8 isn't made a whole lot in here in any case.
The remaining seven slots in the main deck are for your techs. I recommend making them all monsters, since 25 monsters and 15 S/T seems pretty stable. You have some pretty varied choices, and at this time I have several variations.
Worm Engine: 2 Chaos Sorcerer, 3 Worm Xex, 2 Worm Yagan.
This is nice because it adds more fuel for BLS, and the Xex-Yagan engine is pretty good. If you run it, I recommend Lavalval Chain in the extra, since the deck makes rank 4 easily and it can recycle those Yagan while setting up more plays.
Tengu Caius: 2 Caius the Shadow Monarch, 3 Reborn Tengu, 2 Genex Ally Birdman
I've used this for a while now. Caius is powerful, Birdman recycles stuff, and Tengu is just great. Optional -1 MST, +1 Pot of Avarice for recycling, since Tengu ditches a lot. I recommend Locomotion R-Genex for the extra as well, since with both Birdman and Caius available, you can make it and just win games.
Twilight: 2 Chaos Sorcerer, 2 Thunder King Rai-Oh, 2 Tragoedia, 1 Caius the Shadow Monarch
Sorc is powerful, Rai-Oh controls the opponent without the need for backrow (which is good because you wont be running any), Trag is big and you'll usually have a decent hand at the start of the game at least, and Caius is just good. Suggest Arcanite in extra here.
Tengu Breeze: 2 Tragoedia, 3 Reborn Tengu, 2 Blackwing - Breeze the Zephyr
Modern version of the original build I posted. If you're running this, put at least 1 Blackwing Armed Wing and Blackwing Armor Master in the extra so Breeze can go into stuff. Trag over Birdman because Birdman isn't really needed here, and you'll want to use stuff over Locomotion in the extra. Again there is the option of -1 MST, +1 Avarice.
So yeah. Fairly easy to go for tech, just a small engine to run alongside the main build. I will say now though that I do not recommend Dark Armed Dragon. From my testing, if it hits the field, you'll probably win, but odds are high that it wont hit the field, and will just be a dead draw.
