Playing this deck, I always calculate carefully so that the security stack does not run out before I can attack our opponent with OTK.
Reserve more memories with "delay" option card, try to play more tamers, building the digivolution chain for AncientGreymon in raising area and only move out when we have enough option to win the game in one turn.
Deck profile is uploaded below, I made a changed to use Rowdy Rocker instead of Tai, You have grown up for draw power. Actually I want to use 3 copies of Tai Kamiya tamer and 1 copy of Marcus Daimon, but we only have 2 cards of Tai tamer, that's why.
Fill deck list please?

There no need for volcdramon since any greymon will provide the security plus 1.
Yeah this is more or less how i played ancientgrey too. I used rowdy rocker over tai you have grown though
Good idea, so there is no need to return 1 "Agumon" in to bottom of the deck to trigger "Draw 3", also need to have Tai tamer in play. I actually put only 1 card of "Tai, you have grown up" for backup.
