If Dragon's Rage is played to move a unit from the battlefield to base, but Flash is used as a reaction to return that unit to base before Dragon's Rage resolves, does Dragon's Rage still kill a unit?

Ruling: No, Flash blocks Dragon's Rage in this scenario. If the unit is already in base when Dragon's Rage resolves and no movement happens, there is no destination, so the reflexive trigger will not have a valid target and won't finalize.

Sequence:

• Dragon's Rage is played to move a unit from battlefield to base
• Flash is used as a reaction to return the unit to base
• When Dragon's Rage resolves, no movement occurs because the unit is already at base
• Without a destination, no unit can be chosen to deal damage to

Nuances:

• This only works because Dragon's Rage specifies "destination" - if it said "at its location" then the trigger would still work even without movement
• Flash doesn't block Dragon's Rage if the opponent was moving a unit TO the battlefield (only when moving away from it)
