This reminds me a bit of the issue with Blightwing and Warhawk actually, in terms of resolution order:
From a textual logic perspective, since it says, “Create… when I take sSkull damage”, it seems a bit unintuitive for the game to effectively ‘say’ the troop hasn’t taken Skull damage just because it’s dead (I mean, it’s obviously just a flesh/crystal wound).
I get it from the effect resolution order perspective, though, and thank you for the explanation.
Was that aspect of the interaction working as intended? Not a life or death issue for me personally, although I can’t say the same for the Frozen Shieldbreaker!!
