[OP14-013_p1] - Monkey.D.Luffy (The Azure Sea's Seven: Alternate Art)

After using the [Once Per Turn] effect of my "PRB02- 002 Trafalgar Law", I then use this [Activate: Main] effect to swap the power of "PRB02-002 Trafalgar Law" with that of "OP14-013 Monkey.D.Luffy". In this situation, what would the power of "PRB02-002 Trafalgar Law" become?

The base power of "PRB02-002 Trafalgar Law" would become 0, and since the effect from "PRB02-002 Trafalgar Law" is giving −2000 power, the card's power would be −2000.
