Mirror Garden:
So, this one was actually very hard. For the simple reason I know two versions if the seven deadly sins. One in which Pride is trade with Proud or Vanity. But I think I can give you another one. 
So, Mirror Garden is less or more the evil brother of Mystic Garden. Everything in this garden from the leaves to the wood of the tees is made of reflecting objects. Because the Mystic Garden Shape shifts, some believe the Mirror Garden is the Mystic Garden.
And this garden also have a Tester, and this is someone everyone will know. As you walk trough the garden, whispers will start to show. You have a feeling like someone is watching you. He, or she, will whisper things like ‘Look to me.’ ‘Please look to me.’ The urge to look up at one of the trees is heavy, some are weak and will look.
When you look to one of the trees are the flower you will see yourself, but in a very twisted way. The once that look to you is more beautiful then you are, like you always wanted to be. But his face is twisted, grinning and smirking. He offers you to become him if you will switch places with him in the mirror. If you take the offer he will pull you inside the mirror which will explode after that. Mirror garden just claimed your soul and will use the energy to repair the reflecting object.
Which leads to one conclusion, you are your own Tester. Is your pride is flow and your will you will pass the Garden easy. The moment you step in the test begin and the moment you step out on the order side it ends. You have to take the test every time you want to pass. That makes the Pride test one of the most dangerous once, since you have to take it more then once.
The guardian of the Pride test is Sunni Gummi

But, that isn’t the end if this Test. There is some kind of reward. I don’t know yet which one. You could say I have to take the test of pride myself yet. If anyone took the test before me and is willing to tell me the reward he found I can add it.
