Set Cipher Soldier. Jaden will attack it once and won't have anything to attack over it once it is face-up.
Heal every turn with Golden Ladybug and Solemn Wishes.
Activate Spirit Barrier so that you do not take any battle damage. Summon 2 Unhappy Girl to later use as tribute Fodder.
Use Shard of Greed and Good Goblin Housekeeping to draw into your deck.
In case Unhappy Girl is the last card in your deck, you can use Double Summon to summon her and The Winged Dragon of Ra during the same turn. You can also replace Double Summon with another Unhappy Girl so that you are sure to draw 2 Unhappy Girls before your final turn.
During your final turn, summon The Winged Dragon of Ra and give him your accumulated LP to use as attack.
Transcendent Crystals Send 1 to 3 cards from your hand to the Graveyard. Choose the same number of "Crystal beast" monster(s) from your Deck as the number of cards you sent from your hand to Graveyard, and place it/them tin your Spell/Trap Zone as. This Skill can only be used once per turn, and twice per Duel.
I replaced my Crystal Seer with Grave Squirmer, it worked great so far. Since Neos Knight won't make any battle damage, I can swing my Grave Squirmer into it to trigger its effect. I hope next Yubel event give us another great card like this
Phantom Skyblaster is really a nice idea. Costing less cards in Cipher deck and leave a room to put Anti-Magic Arrow
You were just unlucky thaf Jaden still had Neos Allius on the field at your last turn. Usually Jaden's last turn monsters are Neos Knight, Neos, Stratos. He is rarely keeping Neos Allius until the last turn
he used it on the ciper soldier once only. he pretty much gives up when you have so much life points. especially with the draw power when you get really low cards he relies on winning by deck out since your life points are so high. but even with gemini spark if you should have 3 monsters plus extra in your hand, so that wont be a worry
