Gem Knight Decklists
Shaddoll Gems

With a combination of two amazingly aggresive decks, Shaddoll Gems can easily spit out much over 8000 damage in a single turn. With all the Gem Knights being EARTH and Lady Brilliant Diamond being LIGHT, the deck is able to bring out a wide range of El Shaddoll Fusion monsters each turn.
The Gem Knights have great synergy with Shaddolls as their monsters both get effects when sent to the Graveyard for a Fusion. With a combined total 14 Fusion Spell cards, this deck can easily play around your opponent's Trap cards. However, to ensure a quick one turn kill, Denko Sekka is included. Being a LIGHT is also useful for making El Shaddoll Construct.
While the deck may not be tier one, it is extremely explosive and can win games in single turns.
