If a unit has both 'must be assigned combat damage first' (like Shen/tank) and 'must be assigned combat damage last' (like Caitlyn) effects, which takes priority?

Ruling: When multiple units have combat damage assignment restrictions, you must follow the order: units that must be assigned damage first (tanks), then normal units, then units that must be assigned damage last.

Sequence:

• Assign damage to units with 'must be assigned first' effects (like Shen/tanks)
• Assign damage to units without restrictions
• Assign damage to units with 'must be assigned last' effects (like Caitlyn)

Nuances:

• The exam question appears to have been poorly worded, asking about a single unit with both effects rather than multiple units with different effects
• If a single unit somehow had both 'first' and 'last' text, that would be a contradiction
