Can Unlicensed Armory be played as a reaction to save a unit from a spell that would kill it during the opponent's turn?

Ruling: No, Unlicensed Armory cannot be played as a reaction to save a unit during the opponent's turn because it does not have the Reaction timing keyword.

Nuances:

• If the card had Action timing instead, it could be played at Action speed (during your turn or in showdowns), but Unlicensed Armory does not have this timing either
