Chaosmon

Granted a consistent 3-memory at the start of your turn (from either tamers Mimi or Ken Ichijouji), you can digivolve into Chaosmon through a LV5 digimon with <Digisorption> (either [BT2-047] Argomon or [BT3-054] Blossomon) by suspending yourself, subsequently into [P-025] GranKuwagamon. Use GranKuwagamon's <Digiburst 2> to grant yourself <SecurityAttack+1> (once or twice) and then digivolve into Chaosmon, resolving his effect to attack any of your opponent's digimon. So with the combo GranKuwagamon with 4 digivolution source and then digivolve to Chaosmon, this combo can check security up-to 4 cards in one turn. Using Hidden Potential option card is a must to save 5 costs when digivolving.
