(Disclaimer: This deck requires you to have fair amount of APM. As long as you attach at least 10 materials to Digital Bug Corebage, you can make it to the top with C9 for fatal explosion.)
Hey! These insects are bugging me. Let's flip them up and down, shall we?
Gameplan
1) Reach the board state as illustrated:

- First of all, although not seen in this picture, Special Summon "Digital Bug Websolder" with Saryuja. Then, activate Websolder's ability to change battle position of a monster you have -from Attack to Defense- to bring forth second Websolder from your hand. Then, XYZ Summon Scaradiator by using 2 x Websolder as materials.
- Then, use Saryuja and any monster but Chaos/Scaradiator/Panda to Link Summon Reprodocus and line Scaradiator behind it.
- Don't forget to place ME-PSY-YA on Pendulum Zone and Special Summon Chaos Emperor Dragon. It's needed to find Books and Rank-Up spells with "Primal Seed" duo, that's why.
- Also, play "Temple of the Kings >>> Rebirth Judgment" combo to change the type of every monster in GYs to "Insect".
2) As seen above, "Rank-Up-Magic Astral Force" was played. It was to bring forth "Digital Bug Corebage", our main worker for this deck:



- As you can see from these three pictures, in order to attach a material to Corebage, battle position of monster(s) has to be changed. By turning Panda face-down, we can gladly do so. Oh, we have to pick a monster which has to be "Insect" but we already got it covered with "Rebirth Judgment" trick.
- The ability of Corebage isn't hard once per turn. So, as long as we reset Corebage by flipping up and down, we can change battle position of Panda to attach another monster as many times as time limit allows. Try to aim for at least 10 materials...
- Fortunately for you, "Primal Seed" duo can find Book spells in addition to Astral Force because your job isn't over yet.
3) When you have attached at least 10 materials to Corebage, activate Astral Force to bring forth Rhinosebus. Then, change its type to "Machine", which allows you to bridge into Number 9 with Astral Force for last time. Finally, seal the game by activating Barian's Force to bring forth Number C9:








- For context, total damage inflicted was 300 x 13 + 800 x 13 = 14300 damage, which results into FTK with a bit overkill.

If you wonder how to save up some SR and UR points, I can show you:
- "Digital Bug Scaradiator" and "Digital Bug Rhinosebus" can be collected for free, if you have acquired "Growing Digital Bug" structure pack from PvE mode in "Digital Bugs in Cyberspace" chapter to save 30 SR and 30 UR! Alternatively, you can also find them in "Legacy Pack", if you haven't completed said chapter.
- "Pot of Avarice" can be collected by purchasing "Re-Contract Universe" deck. 90 SR saved and you can try a new deck!
- "Rebirth Judgment" can be collected by purchasing "Cybernetic Successor" deck. 30 UR saved and you can try a new deck!
- "Primal Seed" + "Pot of Acquistiveness" can be found within "Legacy Pack" to save 30 SR and 60 UR!
- "Temple of the Kings" can be found within "Guardian of Kings" Secret Pack to save 30 SR!
- "Into The Void" + "Allure of Darkness" can be found within "The Infinite Void" Secret Pack to save 180 SR!
- "Number 60: Dugares the Timeless" + "Rank-Up-Magic Astral Force" can be found within "Number Recall" Secret Pack to save 60 SR!
- "Rank-Up-Magic Barian's Force" can be found within "Sword of the Seventh One" Secret Pack to save 30 SR!
- "Number 9: Dyson Sphere" can be found within "Colossal Mech" Secret Pack to save 30 SR!
- "Formula Synchron" can be found within "Stardust Ties" Secret Pack to save 30 SR!
- "Wonder Wand" and "Spellbook of Knowledge" can be collected by purchasing "Spellbook of Prophecy" deck. 120 SR saved and you can try a new deck!
So, in total, you can save up to 630 SR and 120 UR, if you are willing to spend some gems. Other SR and UR cards I didn't mention are essential.
That's all for this one. If you have any questions, feel free to ask. Have fun in Master Duel!
