If I try to play Sacrifice but there are no enemy units on the board, can I still sacrifice my Mighty unit as the cost?
If a player forgot one of their units no longer has enough Might to be Mighty, must they choose another Mighty unit, or can they not play Sacrifice?
When I Sacrifice a Deathknell unit like Herald, what resolves first — the Deathknell or Sacrifice's draw 2 and channel? How does Baited Hook interact differently?
Can I exhaust runes whenever I want, even outside a reaction window? Also, can leftover runes from last turn be used before the Awakening step on my turn?
Can I respond with Tactical Retreat and then Sacrifice on the same unit, or must Sacrifice's kill happen before I can Tactical Retreat?
