Q1: After using this card, I digivolve a red Digimon into a white Digimon card. What color card can I trash from my hand to reduce the memory cost of the digivolution?
You can trash a red Digimon card to reduce the digivolution cost. The card you can trash with this effect must match the color of the Digimon performing the digivolution in your battle area.
Q2: I’m digivolving a Digimon in my breeding area. Can I reduce the digivolution cost by 4 with this card's effect?
No, this effect can't reduce digivolution costs of Digimon in breeding areas.
Q3: During the turn I use this card, if I have a blue Digimon in my battle area with an effect that reads, “This Digimon is also treated as red,” can I trash a red Digimon card in my hand to reduce the digivolution cost by 4?
Yes, you can.
Q4: After using this card, I activate BT7-085 Takuya Kanbara’s Main effect. Can I use this card's effect specifically to trash cards with Hybrid in their traits from my hand, so that I can place them under Takuya Kanbara using its effect?
No, you can't. You don't trash the card in your hand with this effect until you digivolve. BT7-085 Takuya Kanbara’s Main effect reads, “You may place 5 cards with Hybrid in their traits from your trash under this Tamer in any order,” and is used to digivolve into EmperorGreymon. As such, you place the cards under Takuya Kanbara before you begin digivolving, at which point you can trash a card in your hand with this card's effect.
Q5: When digivolving from a multicolor Digimon, what color cards can I trash with this card’s effect to reduce the digivolution cost?
The card you trash can match any one of the Digimon’s colors. For example, when digivolving a blue/green Digimon, you can trash either a blue or a green card.
Q6: Can I reduce the memory cost of a DNA digivolution with this card's effect? If I can, what color cards can I trash with this card’s effect?
Yes, you can. The card you trash can match any of the colors of either Digimon. For example, when DNA digivolving a blue Digimon and green Digimon, you can trash either a blue or green card.
Q7: After using this card, can I reduce the digivolution cost of my digivolving Digimon by trashing 1 Digimon card in the hand with the same color when an effect to digivolve one of my Digimon is activated?
Yes, you can.
