With the expansion each trainer receives another 30 cards for each team. The game becomes more interesting with a few new rules thrown in as well affording new possibilities and tactics.The Wild Bunch now get 'Felix, der Wirbelwind' and 'Maxi 'Tippkick' Maximilian' and the Unbeatables get 'Atsche Gratsche' and 'Rotze' so each trainer can immediately swap out two players. A 4th and 5th card for all other players are also added to the play mix with new special abilities.Each trainer can now assemble a crafted team of players with special abilities such that the opposing trainer won't know which team members they'll be playing against. - BoardGameGeek
