Sala/Gato X line provides a lot of draw power and aggression with constant free digivolutions.
Rize X cards provide SO much value with free tamers and a DP reduce bomb when going from Rize to Rize X
Rasen cards can be used on top for a lot of aggression (Fury with Rize under into Rasen can be 4 easy checks) or to stop your opponent from keeping any bodies on the field with Rasen's Digi-burst
The tamer package helps with consistency via TK, scare tactics to your opponent with TK/Kari, and Tai/Kari will skyrocket your memory as the game progresses, as well as keep your Neferti, Rize, and Rasen stacks safe.
