So if I have one Natsumi (NtS) in play and I see 2 to 3 Cards in hand with using Way of the Scorpion (WotS) or Uncovered Plans (UP) I assume that if one of them is a Battle Strategy then her ability takes affect.

But what if I have 3 NtS in play. I use UP and Interrupt with all 3 NtS. Now lets say I reveal only one Battle Strategy, then I assume that all NtS affect that one card. What if 3 Battle Strategies are revealed by UP (or 2 in the case of WotS). can I: a) use all NtS on one Strategy? b) use one NtS on each of the Strategies c) use two NtS on one Strategy, and one NtS on a second Strategy? d) any combination that I choose?
