I have yet another timing question:
Normally, the three white ones would die due to Elesh Norn's ability (-2/-2).
BUT can I first sacrifice them with Teysa's first ability in order to remove Elesh Norn from the game?
I am not sure about the timing. Elesh enters the battlefield and his ability resolves. Can I react to that with creatures that would be affected by this ability (-2/-2)?
