Underdog

The underdog bonus triggers and gives rewards when you win while having significantly fewer trophies than both your team and the opponent.

Slurp! The underdog system is a benevolent system that protects users in unfavorable matchups, hmph! It activates when there's a large trophy difference between teammates or when the opposing team is significantly stronger, granting rewards. Earn extra trophies upon victory and minimize losses upon defeat, so use it wisely, hmm!

I don't know much, but good luck!

This means a situation where you get bonus trophies even though the opposing team has more trophies and your team has fewer, but you still win!!!
