QI attached hBP06-103[Matsurisu] to a [Natsuiro Matsuri] on my stage. When rolling a die during my next turn, I use the ability of hBP06-103[Matsurisu] attached to a [Natsuiro Matsuri] and changed the result of the roll to 4. After that, I used hBP06-074[Natsuiro Matsuri]'s collab effect "Among Angels". In this case, does the hBP06-103[Matsurisu] archived during this turn count as "for each support card you used this turn"?

ANo, the collab effect "Among Angels" only counts support cards played from the hand during that turn.

QFor the "for each support card you used this turn" of hBP06-074[Natsuiro Matsuri]'s collab effect "Among Angels", does it count the cards attached to holomem from areas other than the hand, for example by hBP01-003[Aki Rosenthal]'s Oshi skill "Survival Power"?

ANo, the collab effect "Among Angels" only counts support cards played from the hand during that turn.

QFor the "for each support card you used this turn" of hBP06-074[Natsuiro Matsuri]'s collab effect "Among Angels", does it count the support cards used after collab?

ANo, it only counts the number of support cards used up to the point that the collab effect "Among Angels" is used.
