When using Temptation with Repeat, can you effectively swap two enemy units' positions, or does the second activation fail because the game state has changed?

Ruling: The second activation fails. After the first activation moves a unit, the game state changes, and when the repeated activation checks legality, the original target location no longer has a unit to move to, causing it to fail.

Sequence:

• First activation resolves, moving one unit (e.g., Battlefield A unit to base)
• Repeat cost is paid for second activation
• Second activation checks legality and finds no valid target at the original location
• Second activation fails to resolve
