I'll explain the last event that had the same concept. Previously we needed to finish the Looking for Mr. Right event over and over and over and over. The server that had the most finished events won the Vegeta card. The losing server received Yamcha.

This time there are more this that contribute to the total amount. Not 100% sure what is was anymore but if I remember correctly it is the amount of Piccolo's (from a new event), amount of friend summons, amount of training session and I think more things also. These amounts will get tallied up and the highest number wins.

It's just "do this thing as much as possible". When it will start you will get a notification in your news what you need to do. They will explain it that way.
