I am aware that it would make more sense to play 3 copies of certain cards, such as Girsu. However, I only make decks with cards I actually own in real-life as I want to be able to play with what I have.
The most important card in the deck is the field spell Heavy Metal Raiders, as it can protect your monsters in battle and help you summon out more in the process.
This deck is definitely not a combo deck, but there are some fun plays/strategies you can apply:
If you manage to draw Cyber Stein in your opening hand, you can attempt to use his effect to special summon The Last Warrior From Another Planet.
Crackdown/Mind control can be used together with a level 6 monster in order to facilitate the summoning of Dhampir Vampire Sheridan.
If you are prepared to take some damage to your life points, you could main deck Jinzo #7 while having Heavy Metal Raiders in the field zone. For example, say your opponent attacks your Jinzo #7 with a Blue-Eyes White Dragon. After taking the damage, your Jinzo will now have 3000 Atk, while once per battle phase being unable to be destroyed in battle, with the ability to attack directly for a lot of damage.
