For someone using a Deck Destruction strategy, Breau had actually been quite lucky.
A Deck Destruction strategy obviously meant destroying the opponent's Deck, whittling it down to zero cards until they could no longer draw. Under the rules, that meant they lost. A duelist with no cards left in their Deck had no right to continue fighting; that was a basic rule.
But unlike Life Points, which were fixed and equal for everyone at the start of a duel, Deck size really did vary from person to person.
Most of the Decks Kira used in the anime world were actually bulky sixty-card Decks. As analyzed before, the thicker a Deck was in the anime world, the more inexplicable cards you could cram into it. That made the Deck more resilient and reduced the odds of suddenly dying because of an impossible Field.
That said, not all of Kira's Decks were bulky ones. He also had Decks that stayed right at the forty-card minimum. For Kira, those Decks were generally gimmick Decks.
That's right, gimmicks. Decks built around a specific one-turn-kill combo, summoning a specific Monster like when he had summoned Ghod in one turn against Lua, or targeting a particular Infinite Loop.
In short, the entire Deck existed to serve a certain combo. In that case, there was no need for too many meaningless cards to improve its resilience. On the contrary, the fewer cards in the Deck, the easier it was to complete that combo.
Such Decks were great for messing around or crushing opponents whose Duelist Level was far below his own, but they performed less reliably than more conventional bulky Decks against strong opponents.
Breau had been lucky. The Deck Kira was using today happened to be a standard forty-card Deck. To a Deck Destruction user, that
