Famous trainers from all around the world have been invited to the Tag Force Cup, including Gym Leaders, Pokemon Professors, Elite Four members, and so on. With so many trainers, the sole unique concept of the Tag Force Cup comes into play: partner up with one of them, with a new partner every day. May the best duo win.
Every three days real-time is equivalent to one in-game day. Though you can have any number of Pokemon, you must form a party of only three at the start of the in-game day. In addition, a list of available NPC partners will be posted, along with three of their Pokemon. Then, it's first come, first served: whoever meets that NPC in-game first partners with that NPC for the rest of the in-game day. The sole rule here, as mentioned above, is that you cannot have the same partner two in-game days in a row.
From there, all you do is battle the other players and their partners, in exciting double battles. At the end of every in-game day, three players receive a relationship bonus with their partner of the day: the one player who won the most battles, and the two players who worked best with their partner (i.e., who RPed their NPC partner the best). The two best duos are determined by a panel of three judges--the GM and two chosen players. A high relationship bonus with certain partners may unlock stronger Pokemon for that partner, or even secret partners.
Lastly, every fifth in-game day (after twelve days real-time) is a Tournament day. After forming their partnerships for the day, a single-elimination tournament will be set up for all the players. The winner receives a higher than normal relationship bonus, and possibly other rewards. Partners:
