I've been dead set on getting Kiora as soon as she's available, and soon she will be. However, that Nissa 3 tho.. If you could re-roll Kiora would you still get her, or is that new Nissa a better option?
I'm going with N3 -- working my butt off to level her so she can replace Kiora. Currently playing the same deck and N3 has a much better win rate in Standard. Will probably still use Kiora for legacy.
