So this idea is fairly "out there", the "Crated Djinn" would be a brand new obtainable item. First off the basic run down of it: Obtainable from any form of crate, end round drop, chest, or rolls. The only thing is the chance of obtaining this would have to be rarer than a godlike or up to Brass (I'd prefer the 1 in 500k chance just to make it extremely valuable). The Djinn would only be allowed to be used in the Lobby server, when used it summons an NPC named "Djewran" (With the latest update it'd probably be possible to only stream this npc to the player who uses the Djinn). Djewran will then prompt you with a message "You think you were getting a real Djinn?! Hahaha. Fool, I'm the Greediest of all Djinns and do not allow for your petty 3 Wishes nonsense. I'll only give you 1 Wish. So decide, and hurry my Rice is burning."
After this message 4 Options will pop-op in the message box:
1) Wealth Beyond Imagination (This is a random amount of coins that are extremely better than the ones obtained from Gift Packages and are scaled to level)
Djewran: Ahh.... I guess you want to compete with me eh?
<Username> has acquired X Coins!

2) Ultimate Power (Instantly levels you up 2-5 Levels, If you're at Terran's level this would be extremely useful)
Djewran: What, Killing seems to hard for you now?

3) Discarded Loot:
Djewran: I could've guessed this being your wish. Here you go, pick your salt pills.
(A new menu pops up with the message containing "You must now select 1-3 Amount of Crates" Purely up to Brass how many, but I suggest 3 just because of the chances of getting a common. You now see every Seasonal Crate that has been expired before you, you get to select 3 of them that you take. This would just be another way to reinvigorate the market with guns that may never be seen again , but since this is extremely rare this wouldn't harm the economy in any way.

4) New Found Friendship (You gain 1-3 Random Crates, a small amount of coins)
Djewran: You didn't want to run me dry? Well here you go, a small token of friendship
<Username> has acquired an Empty Crate (I guess this is optional as it'd just be a great cosmetic if possible to add or make it a badge style'd item just as a sort of collector's thing.

Afterwards Djewran disappears in a sort of smoke and leaves you with your assorted treasures.
