Scrap is an archtype that focuses on self destruction and despite their name "Scrap" and their appearance, only some of them are machine types such as Scrap Mind Reader and Scrap Breaker. A pure Scrap deck can be considered stable enough to compete with a strong meta-deck like Blackwing, Lightsworn and Six Samurai but I guess it is still outmatched by them.
All Scrap tuners has an effect that is triggered if they were destroyed by the effect of Scrap cards, including destroyed by their own effects because it is still considered Scrap card due to the name that consist the "Scrap" word. Up till now, Scrap has only 4 synchro monsters as their ace, but only 2 of them are mostly used which is Scrap Dragon and Scrap Twin Dragon while Atomic Scrap Dragon is seldom used due to the requirements that needs at least 2 non-tuners which makes it difficult to summon it, plus due to its effect that not always useful to compare to Scrap Dragon and Scrap Twin Dragon despite being the strongest of all 4 of them. While the new release, Scrap Archfiend can be summon easily by using Scrap Chimera and Scrap Goblin but due to it being a non-effect synchro monster similar to Gaia Knight - The Force of Earth and Naturia Leodrake, it only serves as a quick power house rather than full Scrap deck support.
There are many non-Scrap card that boost the capability of Scrap deck such as Geartown and Ancient Gear Gadjiltron Dragon for an instant 3000 ATK beat stick with the ability to seal spells and traps when it attacks. Destroying Geartown for Scrap Dragon's and Scrap Twin Dragon's effect is the most common combo used. There are other cards that their effects will triggered when destroyed, such as Limiter overload, Widespread Dud, Wild Tornado and Blast With Chain. Limiter Overload is definitely not a favorite as it doesn't serve Scrap deck that much as it just special summon Speed Warrior from your deck, hand or grave when it is sent to grave. Contrary to Widespread Dud, Wild Tornado and Blast With Chain where their effects definitely gonna come in handy when combined with Scrap Dragon or Scrap Twin Dragon. The very first Scrap monster card that was released is Scrap Recycler, but this card doesn't quite helpful to be used in Scrap deck, I'll say it is way better to include it in a Gadget deck rather than Scrap despite having the word "Scrap" in its name, it is still treated as Scrap card, but doesn't serve Scrap deck that much good.

Some people like to include the Meklord Series in Scrap Deck to further improve number of easy beat stick as Scrap focuses on self destruction, and if the the destroyed card is a monster card, certainly it will trigger the effect of either one of the trio Meklord monster, Meklord Emperor Granel, Meklord Emperor Wisel and Meklord Emperor Skiel. Though Meklord Emperor Skiel is not a favorite to include in this deck as its effect prevent other monster you control from attacking and being one of the trio with the lowest ATK. Meklord Emperor Wisel also has the effect that seal your other monster from attacking, but due to its effect that is able to negate the activation of opponent's spell card once per turn, it serves as a partial Legendary Six Samurai - Shi En in Scrap deck and definitely gives your opponent a hard time just to destroy it.

Another card that support Scrap deck is Green Baboon, Defender of the Forest. As it seems that most of the level 4 Scrap monster are beast type, focusing in summoning Green Baboon, Defender of the Forest is not a bad idea. Beast deck properties have a massive draw power gained from cards like Horn of the Phantom Beast and Beast Burial Ritual. Both of these cards is advised to be included in such deck in addition to the existing Scrapstorm that serves as the self-destruction, draw power and deck search when combined with Scrap tuners.

The above deck is used by Andre in Yu-Gi-Oh Tag Force 6, after certain modification of course, because this is taken from his 4th deck as it is set when you include a forbidden card in your deck while he actually uses a lot of forbidden card in this deck such as 3 Graceful Charity for extra draw power and dump Green Baboon, Defender of the Forest and also 3 Foolish Burial to easily send Green Baboon, Defender of the Forest to grave or Scrap Monster. As you can see, from the way it looks, this deck doesn't utilize the Scrap synchro's ability at all just to maintain the fact that this deck is fully beast monsters making all monster cards are power houses due to Solidarity.
Such deck is a double-edge sword as it doesn't provide you with a strong back rows that can save you from opponents counter attack even if it does give you a massive ATK boost.
Due to such weakness, I edited this deck from being a full fledge beast type Scrap deck to a mostly beast type Scrap monster deck that can utilize the Scrap synchro's effect.

I included Destruct Potion to give this deck a bit of an endurance especially after using Green Baboon, Defender of the Forest's effect for so many times. The Rank 4 xyz monster included is due to the easiness of swarming two level 4 monsters on the field, especially by Scrap Chimera's effect, but I strongly suggest that you go for synchro summoning Scrap Dragon instead of xyz summon a Rank 4 xyz monster. Horn of the Phantom Beast is for surprise ATK boosters and draw power while Scrapstorm and Beast Burial Ritual are also for draw power, but can be chain to waste opponents card like Mirror Force, Dark Hole, Dimensional Prison etc.
