If I had a 7 might unit defending, and the opponent had a stunned 7 unit and a 4 unit, would my 7 unit die?

To provide an accurate ruling, I need to clarify the situation. You mentioned a "7 might unit" and a "stunned 7 unit." Since "7 might" is a stat and not a card name, I cannot look up the specific cards to see if they have any unique abilities (like Tank, Shield, or triggered abilities) that would change how combat damage is assigned.

However, based on the Core Rules and RiftJudge FAQs regarding combat, here is how the interaction works generally:

The Ruling

Whether your 7 Might unit dies depends on how the opponent assigns their combat damage.

1. Stunned Units: According to Rule 423.1.b, a stunned unit does not contribute its Might to damage in the combat damage step. Therefore, the opponent's stunned 7 Might unit contributes 0 damage to the combat damage pool.
2. Combat Damage Pool: The opponent's total damage pool for this combat is 4 (the Might of the unstunned 4 Might unit).
3. Assigning Damage: During the Combat Damage Step (Rule 460.2.c), the opponent (the attacker) assigns their 4 damage to your units.
4. Outcome: Since your unit has 7 Might and the opponent only has 4 damage to assign, your unit will have 4 damage marked on it. Your unit will not die, as it requires 7 damage (lethal damage) to be killed (Rule 460.2.c.2).

Important Nuances

• Lethal Damage: A unit is only killed if it has damage marked on it equal to or greater than its current Might (Rule 460.2.c.2).
• Stunned Units in Combat: While the stunned unit does not deal damage, it is still a participant in the combat. If your unit has enough Might to deal damage back, you can assign damage to the opponent's units, including the stunned one.
• Exceptions: If either of these units has an ability that modifies how damage is assigned (e.g., Tank), or if a spell is played during the combat to change their Might or deal additional damage, the outcome could change.

If you can provide the names of the cards involved, I can give you a definitive answer based on their specific abilities.
