This is outstanding content and analysis. Thank you for sharing the data. I think it is important to note that Halo Wisp really needs Kobold of Burden in the lineup for the pinpoint ability which guarantees sneak will always hit. Without KoB, Halo Wisp only has 1 speed and is much less consistent hitting those important sneak attacks.
I wonder if one cam run hybrid Grix lineups that also include Rila Fen to counter the opponent's Grix. I've been trying that a lot lately.
