The new "Supreme Darkness" series brings back the "Evil HERO" modern monsters in an impressive way. The evil versions of the Elemental Heroes Bubbleman and Prisma return, along with the new version of Neos, which has the ability to take over your opponent's monsters. There are many "Evil HERO" Fusion Monsters to choose from, and this collection adds even more, as well as new support cards for easy use.

The series also introduces new "Spheroid" cards that facilitate Synchro Summoning. Two new Pendulum/Tuner Speedroid monsters are here, as well as new Synchro Monsters based on Yugo's preferences, including the largest "Clear Wing" Synchro Dragon created to date.

Fans of Synchro Summoning can discover new "Crystron" monsters, including a new Synchro Monster. There is also a new Level 2 Tuner that can Special Summon a "Crystron" whenever the opponent activates an effect, followed by an immediate Synchro Summon.

Trap Fruad cards, which function as Continuous Trap Monsters, are also introduced in the new series, offering continuous boosts to all your Warrior monsters. When necessary, these Trap Cards can become Warrior monsters and return to the Spell and Trap zone to come back later when needed.

Supreme Darkness includes a total of 101 new cards, including a new World Premiere theme and 25 Quarter Century Secret Rares, including a special card, as part of the 25th anniversary.
