Made by a beginner player slowly piecing together a deck for the first card that caught my eye: Lampmon! I actively chose not to include Venusmon despite her synergy with {Security A. -}, because if I did I feel like she would end up stealing the spotlight over Lampmon... I might cave in and add her once I finally play some games with this list, though. Also this deck would love to play Patamon P-122, but it's way too pricey for me.
I'm playing a lot of cards at only 1 to 2 copies mainly because I want to see how they play; once I find out what feels good I'll tinker with the ratios.
