This is my updated Yellow Base ShineGreymon deck. It is a little more straightforward than my other builds but it can be extremely threatening. I know running the Bt17 Marcus is a little strange but when used with Burst Mode can be an extremely high powered finisher by converting more Marcus's into Digimon that can attack. Other times it becomes a blocker that returns to security to heal you and then comes back as another blocker. It can help a lot.
