Say that I have activated the Trap Card Shattered Axe on my opponent's monster:
Activate this card by targeting 1 face-up monster on the field. During each of your Standby Phases: It loses 500 ATK. When that target is destroyed, destroy this card.
Before I get a chance to attack it in battle, my opponent manages to tribute the target. Does this mean that the target is "destroyed", and thus Shattered Axe is destroyed along with it? Or is the target not destroyed and Shattered Axe remains on the field, despite the fact that the target is no longer there?
I ask because Yu-Gi-Oh! Duel Links (a mobile version of the game) does not destroy Shattered Axe if the target card is tributed. It just sits on the field clogging up space and having the turn counter run indefinitely if the monster is removed by tribute. I don't know if that's a bug or intended behavior.
