Hi there! It has been a while since I played Destiny Board deck. I decided to revisit my old deck and put a new twist. Take as many turns as you like and win the game with Destiny Board. Let me show you.
Gameplan
1) Reach the board state as illustrated:

- After placing "Light Barrier", Arcana was Special Summoned by Saryuja. After choosing the outcome as heads, you can send two of your monsters to GY and take an extra turn. Make sure your side of battlefield is full of monsters but it's alright to miss one or two.
- "Into the Void" was played. Therefore, Sabres + Balerdroch will be delivered to GY, which is what we want. Reason is that you can Special Summon both from GY to your side and use both to take as many turns as you need.
- All traps were set and all of letters will be delivered to GY, which is fine. "Sentence of Doom" can find three letters and "Trap Reclamation" can allow you to repeat "Sentence of Doom" one more time to find last letter.
- Don't change button to anything other than "Auto". Never set to "OFF". "ON" can ask meaningless confirmations, so "Auto" should be fine from now on.
2) It's your turn now, if you have used the ability of Arcana. When you are in Standby Phase, activate your first trap, which is "Destiny Board". Then, chain into "Sentence of Doom" (SoD) but don't use its effect yet when asked to. Start putting letters when you are in Main Phase 1, which is when you should activate SoD. Next, you should chain into "Trap Reclamation" to retrieve SoD after you have put a letter. Although I forgot doing it, I did "Sentence of Doom >>> Trap Reclamation" chain on next turn, not a big deal:

- In case you wonder, Sabres was Special Summoned by shuffling a card you have on top of your deck. Balerdroch has arrived during your Standby Phase, thanks to a field spell present on the battlefield.
- While using the ability of SoD, there is an option related to Fiend monsters. Since Sabres is a Fiend monster, this option will always appear to you until he arrives on the battlefield. Just don't pick up this option by accident or you will miss your chance of putting a letter. Reason is that you can only use one effect per turn and only once that turn. What a harsh condition, this is the example of "hard once per turn" effect.
- As always, don't forget to send Sabres + Balerdroch to GY for extra turn with Arcana.
3) Let's make up for the mistake I did in #2. I forgot "Sentence of Doom >>> Trap Reclamation" chain, but this time, I did. Have a look at pictures for better understanding:





4) For your next two turns, place Sabres + Balerdroch from GY to battlefield. On your Main Phase 1, place your letters with SoD. Then, send Sabres + Balerdroch to GY for extra turn thanks to Arcana, both of which will come back to life anyways. With all five letters present on your board, you win the duel:

So, in total, you can save up to 600 SR and 120 UR, if you are willing to spend some gems. Other SR and UR cards I didn't mention are essential.
