Emerald Call of Chaotic Countdown

Good day to you! In this deck, if you go first and your opponent has only cards in their hand, they will be completely locked out for 20 turns using Final Countdown and Telefon. If you don't know how to play Telefon decks, you can check these guides!

Gameplan

1) When you XYZ Summon Number 60 using 2 x Cthugua as materials, give it to the opponent with "Shien's Spy". Then, Synchro Summon by following this pattern: Librarian + Telefon >>> Stardust + Telefon >>> Ancient.

2) Play "Galaxy Queen's Light" and target on Ancient. Then, activate "Zexal Field" and XYZ Summon C6. You have to use Zexal in order to unlock both abilities of C6 because you need to attach Number 6 into C6.

3) Use C6 to set your opponent's LP to 100. Now, you can activate Final Countdown + SPYRAL Resort + Infinite Hands + Chain Energy and end your turn. Don't forget to use Resort to not deck-out at all costs.

4) When it's your opponent's turn, if they have only cards in their hand, they won't be able to do anything. In addition, due to Infinite Hands, they can't discard their cards at End Phase in hopes of disrupting your setup.

5) Let 20 turns pass and you win the duel with "Final Countdown".

If you wonder how to save up some SR and UR points, I can show you:

- "Zexal Field" can be collected by purchasing "Re-Contract Universe" deck. 30 SR saved and you can try a new deck!

- "Machine Duplication" can be either found within "Rescue Team, Emergency Dispatch!" or "Roid Nexus" Secret Packs to save 90 SR!

- "Into the Void" can be either found within "Life Force Control System" or "The Infinite Void" Secret Packs to save 90 SR!

- "Ancient Leaf" + "Dimension Dice" + "Dice Dungeon" + "Final Countdown" can be found within "Legacy Pack" to save 270 SR and 30 UR!

- "Relinquished Anima" can be found within "Toontastic" Secret Pack to save 30 UR!

- "Mecha Phantom Beast Auroradon" can be found within "Rapid Aircraft Advancement" Secret Pack to save 30 UR!

- "T.G. Hyper Librarian" can be found within "Futuristic Creatures" Secret Pack to save 30 UR!

- "Daigusto Emeral" can be found within "Ties to Mother Nature" Secret Pack to save 30 UR!

- "Number 60: Dugares the Timeless" can be found within "Number Recall" Secret Pack to save 30 SR!

- "Number 6" + "Number C6" can be found within "Timeworn Legacies" Secret Pack to save 30 SR! and 30 UR!

- "SPYRAL Resort" can be found within "Secret Fighters" Secret Pack to save 30 SR!

So, in total, you can save up to 570 SR and 180 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!
