I think the new Dorugoramon (P-184) is a nice tech option to use on the Dorumon (BT17-062) as a second quick stack after cleaning the opponent's table and ending the game. Of course that is the IDEAL play, and won't come very often, but generally I feel this deck could really benefit from one copy to end games faster. We have scrambles and Calling From the Darkness (BT7-107) to get back our pieces more consistently.
I feel like this deck would really benefit from a new level 3, because Agumon is very situational and this deck would prefer much more a dedicated searcher outside of Megadramon (he is the goat), is true tho that this deck has a lot of drawing, but still it would help to the consistency, after all decks this days get searchers for breathing...
