When playing Dragon's Rage, which choices must be declared when casting versus during resolution?

Ruling: You choose the unit you are moving when playing/casting the card. You choose the destination and the second enemy unit during resolution.

Sequence:

• When casting: Declare the unit you are moving
• During resolution: Choose the destination location
• During resolution: Choose the second enemy unit

Nuances:

• You can move a unit between battlefields using this card because only standard moves have battlefield restrictions, not card-effect moves
• The unit can still be moved even if there are no enemy units on the destination battlefield to choose
• Choices made during resolution do not interact with Deflect because additional costs are only paid when determining the total cost of a spell before resolution, not during resolution
