This skill serves as an alternative win method. By gathering all 5 pieces of Exodia parts in your hand with the effect of Exodia the Forbidden One, you win the duel. This skill will be automatically activated at the start of the duel to add the 5 pieces of Exodia into your deck randomly. In total, your overall deck size will be 25.
As of late, the Exodia event consists of many players running beatdown decks. Hence, the rating might not be accurate. With our current card pool that we have, Exodia decks are not too reliable and might not be worth the trouble to win. They have many flaws like dead-drawing a random part and no known way to search for Exodia the Forbidden One from your deck and put it into your hand.
