A special block that lets you resell items you bought from villagers at a higher price, essentially turning trading into a business. Think of it as a “merchant’s stand” or “trading counter.”

Functionality:

When you right-click the block, a custom GUI opens.
You place an item you previously bought from a villager into the input slot.
The block automatically recognizes it and sets a resale price (slightly higher than the villager’s selling price).
Another slot lets you collect the emeralds when someone “buys” the item back (either instantly or after a short timer to simulate trading).

Features:

Price Markup: +10–30% higher than the original villager price.
Emerald Profit: Gives you more emeralds than you spent, essentially making trading a business.
Balance Options:
- Requires fuel (like gold nuggets or paper for “licenses”).
- Has cooldowns so it can’t be spammed.
- Only works with items that villagers normally sell (to prevent infinite duplication of rare gear).

Crafting Recipe (example):

3 Emeralds
1 Villager Head (or Villager Egg in creative mode)
4 Planks
1 Chest

GUI Design:

Input slot: place villager-bought item.
Emerald slot: shows how much you’ll earn.
Collect button: to confirm the resale.

Extra Twist:
If you resell too much, nearby villagers might raise their prices (like simulated “market inflation”), making it a balanced and fun mechanic.
