Space-Time Showdown! Designed to teach new duelists how to duel with friends with a 40-card pre-built deck right out of the box, duelists can then upgrade and build their deck out further with two randomized power-up packs containing additional cards. Super Starter: Space-Time Showdown also gives Duelists an exclusive first look at the newest game mechanic, Pendulum Monsters, an innovative new monster type that blurs the line between Monsters and Spells!

Each starter deck contains:
38 Common Cards
2 Super Rare Cards
1 Beginner's Guide
1 updated Game Mat with new Pendulum Zones
2 Power-Up Packs each with 5 cards from a 15-card set
