Wouldn't Aether Vial or Mother of Runes be a better substitute for DRS if he gets banned? Both seem more powerful than this new Deadeye Tracker. I would also think that green becomes nearly unnecessary if DRS gets banned. Abrupt Decay is the only other green card it really cares about, maybe Sylvan Library or Gaddock Teeg out of the board. I would think there are plenty of other options for DGA than splashing green for those.
