An Armor Control deck centered around Armadillomon, rather than Veemon, and utilizing parts of the Yellow Vaccine engine.
It's designed to get your digivolutions out quickly, while controlling the board via DP-reduction and de-digivolving shenanigans, as well as taking advantage of BT23 Shakkoumon's ability/inheritable to either send out a Lv.4 for free, or continuously activate P-122 Patamon's "On Play" effect.
