Chinese Feud To Go Question

[kaznaka]

"Play during your turn instead of Looking For Trouble...bring back the top monster in the discard stack and fight it.

OR: Add the top monster in the discard stack to the current combat.

Usable once only."

Regarding the 2nd part: Does this mean I could use this card during someone else's combat to add the top monster in the discard pile, or could I use it only during my combat.
