What i did was have a BlackWarGreymon, DoruGreymon and Black Rapidmon for my attackers, then I had mummymon, Seraphimon and Kyuikimon as my replacements. All i did was have my strongest guy attack while the others gave him Hp and MP healers and whenever i had guys die i would send out another guy and revive my strong guy . btw want to match digimon?
