Does Assault trigger go on the chain, allowing the opponent to respond with Gust before the might is added, or does the might apply immediately when the unit becomes an attacker?

Ruling: Assault is a passive ability that applies immediately and continuously while a unit is an attacker. The opponent cannot respond with Gust to remove the Assault bonus if the unit is already attacking.

Sequence:

• Unit becomes an attacker
• Assault passive applies immediately
• Opponent cannot use Gust to remove the Assault bonus at this point

Nuances:

• Assault is not a trigger that goes on the chain; it is a passive effect that applies for as long as the unit has attacker status
