I just got the game the other day and just passed the bit where (VERY MINOR SPOILERS) beat BlackAgumon. My team is made up of a level 12 or 13 Agumon. I want a bigger team so Agumon isn't always fighting by itself, but i have no idea how to get other digimon on my team.
You digi-convert on the digi-farm and put it in your party through the digimon list. To get the digimon you want, you have to fight it multiple times until the data you get reachs 100% --- Listen now : The Battle for Everyone's Souls, Mario Paint http://uk.youtube.com/watch?v=wDl8P0ubMqk
