Timing Reinforcement and The Strongest One

[buffalobob]

Question on using The Strongest One Effect: If you have deployed this turn, each player discards every Ninja they control except for 1.

I have Sasuke (TP2) and Deidara () in play. I activate M865 and chain to reinforcement to Danzo Sacrificing Sasuke. The question is the timing. Because each player discards every ninja and I choose Deidara to stay, Sasuke would naturally be gone. But because of the Sacrifice to bring out Danzo, is this valid or is Sasuke not there to be sacrificed?

Thanks
