How to unlock the Mr. Money in the Bank achievement in WWE 13 - Definitive Guide
Thanks to Irondan316 for the info, you can make the match easier by creating 5 other superstars & editing their stats all down to 1.
This trophy is a lot easier than it was in WWE '12. You can edit your superstar into the match as well, unlike WWE '12. Doing this does not disable the trophy, I attempted getting the trophy this way and it popped when I won.
When you enter the match, immediately get a ladder from outside the ring and set it up. Don't worry about the other wrestlers, they will be fighting amongst themselves and probably won't attack you. Start climbing, and try to pull the briefcase at least twice before you fall off after the AI knock the ladder down. Then just repeat this and hopefully the briefcase should fall. It takes about 4-5 pulls to get the briefcase.
This isn't a difficulty- related trophy, so you can set the difficulty to Easy to make it much easier.
