yugioh star pack 2013 booster box Pack (Yugioh) Toys & Games V set contains Deck themes from the first season of the new TV show Star Pack 2013 - Yugipedia

Every 3rd round, if you didn't pick that character's own partner card, the jerk will force you to use one of their decks, which means no EXP for your partners, because these decks contain THEIR partners with THEIR armors - which is how you get the partners and armors you never obtained yourself into your card library

Alternative and ex versions of Pokmon also count toward completion, while some are explicitly required (their counterparts wont count)
