I then swinged at my opponent's security using Cerberus:Werewolf Mode (with [Rush]) and OmniZwart to clear his 2 remaining security cards, and returned Lilith to hand to trigger Zwart's [When Attacking] effect, deleting 1 of my opponent's unsuspended Digimon with a play cost of 12 or less (not that it matters anyway for this situation).
With all of my opponent's security cards gone, I needed 1 more hit in order to win and here is what I did.
I played the 1-cost option card Calling from Darkness to destroy my OmniZwart in order to return 2 purple Digimon cards from my trash to hand, retrieving GinkakuPromote and a LV6 Nighoggmon. Since my LV7 Digimon with digivolution cards was destroyed, I suspended Analogboy to gain 1 memory, putting the memory counter back to 2 at my side (again, it doesn't matter at this point of game).
I then digivolved my Eyesmon in the field into the GinkakuPromote that I retrieved from trash earlier for 1 cost, and performed the final hit to win the game!
