Cody’s win in this game was extremely close; he was just barely in control throughout, as playing Holydramon directly from his hand right on the first turn gave Hideyoshi enough Memory to put out a completely set-up War Greymon, and Cody’s early attack with Gabumon was punished by a Security Digimon. Cody’s strategy was to play on a damage curve—taking at least one Security every turn he could attack while using counters against Hideyoshi’s to stall them and ultimately pace his opponent out of the game. Holydramon’s high base power prevented Hideyoshi from revenge-killing it with anything but War Greymon himself, as the only Option in Hideyoshi’s deck that could destroy such a high-DP Digimon directly was Gaia Force.
The key plays for Cody were putting down Cocytus Breath to bounce War Greymon back to Hideyoshi’s hand and discard its Evolution Sources, using Holy Flame on the following turn to prevent Garudamon from posing a direct threat even after evolving into that same War Greymon, and putting out Unimon to prevent Hideyoshi from having enough attacks to eke out a win. The takeaway from this that quantity is more important than quality–if Hideyoshi had poured his Memory into poking Cody with many small attacks rather than putting all his eggs into one basket with War Greymon, single-target Options like Breath would be preemptively neutralized. While the additional Security Attacks sound threatening on paper, in practice War Greymon did very little but hinder Hideyoshi this game by eating up his Memory for little real output.
