This issue has happened 2 times, where I get the last kill from an attack triggered on escape. The thing is, the opponent still gets to swap out, but after the turn is done (my attack is done) it ends the match, so I still keep the win.
I want you to imagine the case where the opponent has an OP swap in that ends up killing my creature, then I would lose?
