digimon card game ex03 booster pack from the amazing Digimon Card Game Theme Booster DRACONIC ROAR [EX-03]

5Ds is the era of Synchros, a type of monster that must be summoned using both a Tuner monster (an ability written on the card) and a non-Tuner, both on the field

Any "as [this creature] enters the battlefield" or "[this creature] enters the battlefield with" abilities of the creature will also work
