If a 2 might unit is targeted by En Garde (+1 might, chain 1), then targeted by a 2 damage spell (chain 2), does the unit survive with 3 might and 1 health, or does it die?

Ruling: The unit dies. The chain resolves in reverse order, so the 2 damage spell resolves first, killing the 2 might unit before En Garde can resolve.

Sequence:

• En Garde is played targeting the 2 might unit (goes on chain as link 1)
• Opponent responds with a 2 damage spell (goes on chain as link 2)
• Chain resolves starting with most recent: the damage spell resolves first
• The spell deals 2 damage to the 2 might unit
• Cleanup occurs after the spell resolves, and the unit dies
• En Garde attempts to resolve but its target is no longer in play, so it does nothing

Nuances:

• Cleanup happens after each spell resolves, not after the entire chain resolves
• When a card's target is no longer in play when it resolves, it does nothing
