For Destiny Draw decks, the idea behind it is to use it multiple times by taking damage and healing up to compensate for the damage taken and repeat the process. You get to choose what card to draw from your deck during your draw phase if your opponent deals at least 2000 damage to you regardless whether it is by effect or by battle.
Here are the list of cards you will need during the early turns, with the top having the highest priority and the bottom having the lowest priority:
On turn 7 during Yami Bakura's turn, he should have "F-I-N-A- ". To ensure that you negate his skill to win, you can use the Destiny Draw skill to get Gravedigger Ghoul from your deck. If it is in your starting hand, you can just activate it immediately for safety measures.
Preparations before the final turn
You will need the following cards before the final turn:
Mystical Beast of Serket
Temple of the Kings
Secret Pass to the Treasures
The order is as follows. Activate Temple of the Kings first, followed by Celestial Transformation. You will be prompted to special summon a monster which will be Mystical Beast of Serket. Activate Temple of the Kings's effect to special summon Blue-Eyes Ultimate Dragon from your extra deck. Normal summon Gravekeeper's Vassal. Activate Secret Pass to the Treasures, followed by Union Attack on GK Vassal. Deal the finishing blow with GK Vassal to end the duel.
...it can work, but you will need another card to help you, keeping inmind of ur 6limit of cards held + 3 spell/trap zone... an also dodging bakuras trap card (dont have 2 face down traps/spells at 1 time.
I used this 5 times and it worked just as fine as the deck below, the one I use myself. Auto action unite necrofear, add use serket for blue eyes ultimate dragon, both halved is a total of 1100+2250 = 3350. 3350 + 800 = 4150. This is just not enough for 5k, but I didn't get lucky on the latest released pack for rising energy, if you have it, you can use that to get the 5k total = 10k. Swap it for the golden apples or rain of mercy
