Extend the Story - Add a Room

Agumon has a number of explosive fire attacks at its disposal, even more if you count the attacks you remember seeing an Agumon using in the Digimon Savers: Another Mission video game.

An alternative would be using a card on it - if you brought any, that is. Maybe you could 'imagine' for them to appear in the same way you made your Digivice appeared. It is stupid, but none of the stuff around you makes sense so far anyway.

You turn your head past your shoulder, looking at Agumon with little confidence, while it looks back at you with its jaws parted widely, looking quite confused - and worried - about your next course of action. You could always fight the traditional way - by having it fire its normal attacks. Otherwise, you could always asks of it for some distraction while you do your magic.

Ask Agumon to distract the Yanmamon while you think about your desired card
