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.
No wrath of Neos since the last event. Have all other stuff x3 already.
I used my Cloudian/Ra deck and it can also does the trick at times against Spunky Jaden. Only problem is when he summons Stratos he'll might use it's ability to destroy your field spell so that you're left with no choice but to take damage for that turn unless it's effect is negated by Divine Judgement.
NAH,the silent magician on duel links meta channel is the most consistent.You will almost always open with a spellbook and also silent magician or silent burning to search it out.So far i only didnt have silent magician in my opening hand once only but the next card i drew was silent magician plus you can negate any spell twice
Managed to get a Prismatic Electrum!
I still need a 3rd Core to complete this 100% tough....
thanks for sharing, i believe this is the best deck that is f2p/cheap, just to prevent some bricks, i replaced cosmic compass with The Tricky and those goblins with Warrior Elimination. then its always a win with 95% 8k scores and the rest jaden decked out. Now i need 1 more Elemental Core to finish my farm.
