A deck focused around proximamon and his effects. The main deck focuses on playing gammamon to hopefully evolve into the purple line he has. Then after it dies you can play the proximamon card from your hand. Then the egg deck let's you boost the power and draw cards to prevent from running into issues.
The side deck has a focus of getting the gammamon into your trash faster and the ability to put even more gammamon under your digimon for buffs
