If Lee Sin (orange buff) is buffing a 2 Might unit with a buff (making it 5 Might total), and the opponent uses Watcher to kill Lee Sin, what happens to the buffed unit's Might?

Question

Accepted Answer

Ruling: When Watcher resolves and removes Lee Sin from the battlefield, the buffed unit drops from 5 Might to 2 Might (losing the orange buff), then to 0 Might (losing Lee Sin's passive). If the unit then loses its remaining buff, it would drop to -1 Might, which is treated as 0 Might.

Sequence:
- Watcher resolves, buffed unit goes from 5 to 2 Might
- Lee Sin is removed from battlefield, his passive stops applying
- Buffed unit loses 2 Might from Lee Sin's passive, dropping to 0 Might
- If the buff is later removed, unit drops to -1 Might

Nuances:
- Negative Might values (like -1) are technically possible according to the rules but are treated as 0 Might for all intents and purposes
