If a 4 might unit with 3 damage is targeted by Retreat, and the opponent responds with Stupefy, does the Retreat player still get the ramp effect?

Ruling: No, the Retreat player does not get the ramp effect. Since Stupefy resolves first and kills the unit, Retreat cannot identify "its owner" for the ramp effect.

Sequence:

• Stupefy resolves first, killing the damaged unit
• Retreat then attempts to resolve but cannot identify the unit's owner
• No ramp effect occurs
