If I move Traveling Merchant to an opponent's battlefield and my opponent uses Fight or Flight in response, does Traveling Merchant's ability trigger once or twice?

Ruling: Traveling Merchant's ability triggers twice - you discard 1 and draw 1, then discard 1 and draw 1 again.

Sequence:

• First trigger: Discard 1 and draw 1 (from the initial move)
• Second trigger: Discard 1 and draw 1 (from the second move caused by Fight or Flight)

Nuances:

• The ability triggers twice because the card moves twice total
