Does Gust target a unit based on its printed might or current might, and does damage affect might?

Ruling: Gust targets based on the unit's current might, not the printed might on the card. Damage does not lower might, but effects that reduce might do affect targeting eligibility.

Sequence:

• Check the unit's current might (printed might modified by any effects)
• If current might is 3 or less, the unit is a valid target for Gust
• Damage on a unit does not change its might value

Nuances:

• If a 3 might unit has Discipline played on it (increasing might), it cannot be targeted by Gust
• If a 5 might unit has Smokescreen played on it (reducing might to 3 or less), it can be targeted by Gust
• Spells need to fulfill valid targets to be added to the chain; if no valid target exists, the spell cannot be played
