Metalgreymon has an inheritable effect that allows him to attack the opponent's unsuspended Digimon. When this effect is inherited by Blackwargreymon, he will be able to attack all of the opponent's Digimons, in sequence from the highest DP onwards. DP boost-up can easily gain from using option cards of other Digimon's inheritable effects.
Wow guardromon look broken
Yeah, I understand what you meant.
I mentioned the Guardromon cause I think the MetalGreymon (cyborg) and Blackwargreymon, if they are used in Machinedramon deck it can help to giev more draw power.
Everytime I played Machindramon deck I always feel it lacks of draw power.
