Bronk Stone's Decks

Pre-World Duel Carnival
Bronk plays a "Gearspring"/Machine Deck, which focuses on the manipulation of Gearspring Counters through the effect of his Spell and Trap Cards to grant his Machine-Type monsters additional ATK. He also uses an array of cards to gain an advantage through containing Machine-Type monsters such as "Iron Call" and "Iron Draw".

World Duel Carnival Preliminaries
Bronk rebuilt his deck for the World Duel Carnival. He continues to use a Gearspring/Machine Deck, this time featuring his ace monster, "Tin Archduke".
