Set Kinetic 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.
