Notes & Combos

Fairly standard Elements Unite! farm. It's also very adaptable. The Spellbook engine can be replaced with 3x Jar of Greed, and World Gears of Theurlogical Demiurgy is only required for opponents that have monsters with effects that can get rid of Gate Guardian.

The strategy is simple: On your first turn, play either World Gears or Gate Guardian, and just hide behind it's ATK while you thin your deck with the Traps, Spellbook cards and Thunder Dragon cards.

On your final turn, you should have 0 cards in your deck. Fusion Summon Twin-Headed Thunder Dragon and Normal Summon Gravekeeper's Vassal. Target Vassal with Secret Pass and both copies of Union Attack, then attack directly for game. You'll inflict over 10K effect damage in that one attack.

Make sure as many of your cards as possible are shiny. Twin-Headed Thunder Dragon can be made glossy and then prismatic at the Card Trader (F2P friendly!), and many other cards can be acquired as glossy or prismatic either from tickets or basic luck.

If you already have this deck, go into the editing screen and tap the Menu button in the top-right corner of the screen, then scroll down to change the foil rarity priority. Tell it to replace cards according to foil priority and it will automatically bling out your deck with any foil copies of the cards already in it. After that, just save the deck. (Note: If it's saved already and it won't let you save after doing this, then it's already as shiny as it's gonna get.)
