Now for a tricky one which requires 2 cards to be understood.
ST5-03 features Agumon near static-filled TVs which, given the Parallel BT2-057, seem to be in Metal Empire's habitat (as depicted in the Pendulum Z II).
Going straight into the Start Deck Dukemon, ST7-02 has Agumon (2006) fighting in Digimon Savers Another Mission's Walter Island. This is where the tutorial battle takes place (against a Otamamon nonetheless).
