Team Up Bonuses provide minor stat buffs when a certain pair or trio of characters are in a team together. No one cares about the buffs anymore but this used to be a pretty big deal back when everyone's cards sucked.
It was very impressive when a team of 3 characters filled up all the Team Up Bonus slots, meaning they had a 3-character bonus between them, and all three 2-character bonuses between the pairs of characters.
The Team Up Bonus system is somehow still in the game. Let's have a look at all 56 full bonus teams that currently exist! They have roughly been categorised into character themes.
