When Merchant is moved and triggers its ability, can Gust be used in reaction to prevent the ability, and what is the order of resolution?

Ruling: When you move Merchant, its ability triggers and can be reacted to with Gust, but Gust will not prevent Merchant's ability from resolving. Gust resolves first (checking might), then Merchant's trigger resolves.

Sequence:

• Move Merchant
• Merchant's ability triggers and goes on the chain
• Gust can be played as a reaction and goes on the chain
• Gust resolves (checks might and resolves)
• Merchant's trigger resolves

Nuances:

• You cannot use Merchant's discard/draw effect to pick up a buff card to increase Merchant's might above 3 to negate Gust, because Gust resolves before Merchant's ability
