Unlicensed Armory

Baited Hook kills a unit, then uses information about “the killed unit.” If you prevent that unit’s death, there’s no killed unit, so Baited Hook can’t evaluate its Might. As a result, the check for the Might of the “killed unit” returns a null value, and you’re not able to play any unit. If the unit is killed before the ability of Baited Hook resolves, the outcome is the same.

The intent behind these four cards is to save your unit from dying, whether it died due to direct kill like Hidden Blade or due to lethal damage. To better communicate this, these cards will receive updated wordings. Two of them, Highlander (from the Proving Grounds boxed set) and Unlicensed Armory, have straightforward fixes, adding “heal” and listing “exhaust” and “recall” as separate actions. Highlander [Reaction] (Play any time, even before spells and abilities resolve.) Choose a friendly unit. The next time it dies this turn, heal it, exhaust it, and recall it instead. (Send it to base. This isn't a move.) Unlicensed Armory Discard 1, [E]: Choose a friendly unit. The next time it would die this turn, you may pay [C] to heal it, exhaust it, and recall it instead. (Send it to base. This isn't a move.) Zhonya’s Hourglass also has a slightly updated wording making it clearer that its ability applies any time a friendly unit dies, not just on the turn you play it. Zhonya’s Hourglass [Hidden] (Hide now for [A] to react with later for [0].) If a friendly unit would die, kill this instead. Heal that unit, exhaust it, and recall it. (Send it to base. This isn't a move.) The Boss was mistakenly worded like a triggered ability. It’s receiving updated wording to make it clear that its ability is a replacement effect. The Boss (revised text) If a buffed unit you control would die, you may pay [C], exhaust me, and spend its buff to heal it, exhaust it, and recall it instead. (Send it to base. This isn't a move.) When you conquer, ready me.
