Halloween horrors arrive early in Circuit Break, October's 100-card booster set! Marionettes that move on their own, a mad scientist, and vengeful spirits returning to walk the earth are just the beginning of what you'll find in Circuit Break! This booster is also home to more Link Monsters, including a terrifying new 3000 ATK Dragon that can brainwash monsters it attacks, giving you control over them until their minds burn out. Here's a little taste of what else is lurking in the shadows...

What's that chill crawling up your spine? Circuit Break is infested by a strain of insectoid Mekkstrosities that emulate the human nervous system. They cluster rapidly, attempting to take the form of neurons, and if they succeed, all enemy monsters freeze up and become unable to defend their controller!

Memorable monsters reborn! Famous monsters from history like Sacred Phoenix of Nephthys return in powerful and unpredictable phantasmal forms. Enforce order on their chaos and you'll unlock a cycle of creation and destruction that will only stop with your opponent's defeat!

Powerful cards that can go in any Deck! Circuit Break has a wide variety of cards that let you do some incredible things no matter what kind of strategy you want to employ. You might find a Trap Card that eliminates cards played in the same column as your Trap, or even a brand-new Trap Card that levels the playing field that your opponent will never see coming...because you can play it straight from your hand!
