How can you make your fossil power go up to 250 or higher for a strong attack in fossil fighters

Hi

the more turns there are in a fight, the more power points you will get.
So just don't kill your opponent until you reach 250.

Important to know is that the limit of your power points you can gather in a fight increases as you proceed into the game. To be able to gather 250, you will almost have to complete the game..
