STARTER DECK -Egghead- [ST-29] is Led By Two Strong Leads This bright yellow pre-constructed deck plunges players into the futuristic chaos of the Egghead Island story arc, introducing a technical strategy centered around robotic innovation and trigger mechanics
This means you don't have to devote any time away from pouring energy onto your multiple Munkidoris and can reap the benefits of both a big attacker in the active spot and a ton of chip damage from the bench
