What it does?
You push the top button and a villager will appear before you with his special deal, if you like it, you can save him, which sends him to a safe area where you can easily go to and have access to his trade or if you don't like his deal you can activate the lava and kill him.

Uses -
1. Good for easily picking out good villagers in a survival world and keeping them safe.
2. Might be a method of finding good villagers for adventure maps if you don't have access to MC-edit.
3. Your imagination is the limit!

If you have ideas you would like me try, like a challenge or an idea to keep me entertained you can tell me in the comments, also would you like me to add a "How it works" in the description aswell as "What it does" and "Uses".?
