A deck built around BT4 Kari Kamiya and BT15 Gatomon's [All Turns] abilities to gain memory when your security is removed from.
The core of the deck is a Data/Witchelny build with a Dynasmon top-end.
GAMEPLAN
Inheritables from BT18 Candlemon, BT19 Tapirmon and BT18 Wizardmon allow you to trash from security to prevent them form leaving the battlefield, while BT15 Gatomon and ST19 Tobucatmon provide [Barrier] inheritables.
BT-23 Dynasmon, BT19 Dynasmon (X-Antibody) and BT15 Angewomon ACE provide ways to recover security to stay alive.
Having multiple BT15 Gatomon or BT4 Kari Kamiya allow you to potentially steal turn by giving you memory when your opponent removes from your security, or even when you activate one of your protection effects, limiting the amount of game actions they may take without losing turn. BT3 Mimi Tachikawa and BT8 Takumi Aiba also act as additional taxing effects, though have much less control from your side as to when these effects may steal turn.
WEAKNESSES
This deck probably folds to [De-Digivolve] and DP Reduction heavy opponents. If the opponent is able to generate a lot of memory by stocking up Memory Boost type effects, or many Tamers, the taxing effects of the deck will be significantly less effective. If you cannot create anough pressure by that point in the game, the deck just becomes a poorly focused Dynasmon deck.
