[Start of Your Main Phase] If you have 3 or more security cards, you may add the top card of your security stack to the hand. If you have 2 or fewer, you may place 1 yellow Digimon card with the [Vaccine] trait from your hand at the top or bottom of your security stack. [All Turns] [Once Per Turn] When a card is removed from your security stack, 1 of your opponent’s Digimon gets -2000 DP for the turn.
