This game needs a high-risk high-return mechanism. In a game where everyone wins and the number of Crabadas is increasing day by day, everyone will continue to lose.
An example of a high-risk high-return model: Add Crabada burning feature to Challenge and Tournament section. For example, in the challenge, the losing side should transfer their team to the other side, but 1 of the 3 crabs will be burned and the winning side only wins 2 crabs. Thus, over time, the number of crabs will decrease and the value of crabs will increase.
Of course, this mechanism may cause the formation of whales in the game in the future, a separate mechanism should be developed to prevent this.
