Does Dragon's Rage require you to move an enemy unit in order to deal damage?

Ruling: Yes, you must move an enemy unit to deal damage. The movement must occur first, and then if there is another enemy unit at the destination location, damage is dealt to each other.

Sequence:

• Move the selected enemy unit to a location
• Then, if there is another enemy unit at that location, deal damage to each other
• If no other enemy unit is present at the destination, no damage is dealt

Nuances:

• If the selected unit is killed by a reaction spell before Dragon's Rage resolves, the card becomes illegal and cannot take effect
• The card uses a reflexive trigger structure: you choose the first unit when playing the card, but the second unit choice only occurs if the movement successfully executes
