When I first time see this deck, my eyes immediately focus on tamers Marcus Daimon and Yoshino Fujieda, this is an interesting way of using these tamers. Since the deck has 4 copies of promo BlackWargreymon (a digimon with Digi-burst effect), also the only LV6 digimon of the deck, using Marcus Daimon is a good choice to reset the memory to 3 when starting of the turn and get more memory when BlackWargreymon declares attacking. Yoshino Fujieda, even though she is a tamer for green but she is very useful for any digimon with "digi-burst". If you notice, this deck only uses 4 copies of digitama Kapurimon, and with Yoshino you can return 1 digitama from trash to the bottom of your digitama deck. For each Yoshino in play, you can suspend this tamer to reduce the 1 memory cost of the digivolution for any digimon with "digiburst", so if you have 2 Yoshino in the battle, by suspend both of them, your blackwargreymon only takes 1 cost to digivolve, fast and cheap enough. Beside Blackwargreymon, this decks also uses another 2 "dig-burst" digimon those can take advantage of this tamer.
