Angel of Countdown

Greetings! Once upon a time, I made this deck thanks to Princess and win with Final Countdown. Now, I did it with Chaos Beast instead because what if Princess is banned? Let's find out.

Gameplan

1) Bring forth Tethys by replacing Capricious/Aces/Corobane and draw your whole deck...

• Whenever you draw a Fairy, reveal it to draw another card with Tethys. You can keep it going until you can't draw anymore.
• If you hit non-Fairy, you stop movement. So, continue with Ixchel and alike to trigger Tethys again.
• Always use "Arcana Force XV" in-hand to fetch what would be otherwise brick by Tethys, which is "Light Barrier".
• Know that card draw has to be caused by an effect, not as cost, in order to draw a card with Tethys. For example, using "Upstart Goblin", seen in Side Deck, won't do any help for Tethys but "Into the Void" will. Remember this rule well.

2) If Tethys + Aces are together, Link Summon Insulator with them. Otherwise, place Rain and Lebellman onto Pendulum Zones to Pendulum Summon 2 x Carbon + Capricious + Orange. Also, activate "Final Countdown" and "Light Barrier".

3) XYZ Summon Starring Knight with 2 x Carbon as materials. Then, use Knight to Special Summon The World and pick the outcome as heads thanks to "Light Barrier" to be able to skip your opponent's turn by sending two monsters you control to GY.

4) Synchro Summon Chaos Beast with Capricious + Orange. At that moment, Carbon asks you to shuffle itself on top of your Main Deck, which is essential to not deck-out for 20 turns forward.

5) End your turn and use The World to send Beast + Knight to GY, in order to be able to do what was explained in #3. When it's your move, bring forth Carbon + Beast for The World and repeat until you win with Final Countdown...

• With many LIGHT and DARK monsters available at your arsenal, reviving Beast won't be an issue, provided that you use Beast to retrieve banished monsters into your hand. Afterwards, Pendulum Summon them and use these as resources for The World.
• No matter what you do, don't forget to send Carbon to GY for The World at all costs to not deck-out by accident.

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

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

- "Darklord Ixchel" can be found either within "The Opening Act of an Apocalypse" or "Deceitful Wings of Darkness" Secret Packs to save 90 SR!

- "Trickstar Corobane" can be found within "Essence of Flora and Ocean" Secret Pack to save 90 SR!

- "Tokusano Shinkyojin" can be found within "Crystal Realm Defier" Secret Pack to save 90 UR!

- "Chicken Game" can be found within "The Most Dangerous Race of the Cosmos!" Secret Pack to save 90 UR!

- "Final Countdown" can be found within "Legacy Pack" to save 30 UR!

- "World Soul - Carbon" can be found either within "Hope Sprouting in the Spring Breeze" or "The Ones Who Serve Ra" Secret Packs to save 60 SR!

- "Arcana Force XXI - The World" + "Light Barrier" can be found within "Hand of Fate" Secret Pack to save 30 SR and 30 UR!

So, in total, you can save up to 360 SR and 240 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!
