+1. But I don't think it is possible to show the success/failure cards. You might get away with it always being success, but you would need both success and great success, with the player turning them on and off when needed.
For it to show success/failures, the trainer would have to grab and edit something in the game value wise. This has to in fact exist to mess with it. Otherwise someone would have to mod something in the game that reveals the success/failure cards to you, and that is a WHOLE nother kettle of fish compared to what a trainer does.
