Turns out Glimpse Beyond still draws you 2 cards, if you use it on a unit that has Unyielding Spirit on.

This doesnt make sense since Glimpse Beyond says: "Kill an ally to draw 2".

Since it did not kill the unit with Unyielding Spirit (because it cant die, duh) Glimpse Beyond should not draw you any cards.

Edit: Also what are your overall thoughts on Unyielding Spirit? Ye i know it can be obliterated or recalled, but most of the regions dont have these.
