Mercury Standard 1.0

This an attempt to give You a decent jungling guide for Mercury - The Messenger of the Gods.
I know, that people like to variate and/ or share their experience with me, so please go ahead and...

...put me up to Speed.

This is a given for most jungling:
Help solo lane first!
For Mercury, there is little difference if he gets Orange or Red buff in the beginning.
Start off with your skills as prescribed and if your solo laner has starting problems in his lane, stay there (max. lvl. 4).

Try to always be the first to clear mid camps and if possible do it with your mid laner.
In addition, try to clear buff camps for your allies, so that they can concentrate on their lane. Buy wards from time to time to support them.
Early ganks get more easily, the sooner you get Sprint as an Active (Many people will disagree here, this is just my way of doing it). It helps you to stay near your enemy and get basic hits in.

After Sprint, try to level your Boots first, which is the obvious choice for Mercury.

Your items should now be at least:
Boomba's Mask
Warrior Tabi lvl 3
HoG lvl 1
Sprint lvl 3

Now you need to stop jungling and get into constant ganking. People are more afraid of a Mercury who is everywhere, than of a Mercury who could be anywhere. DO NOT use "Special Delivery" to initiate, if you really don't have to (only if you want to throw someone into tower or into a special skill). "Special Delivery" should be a mean to catch up to your opponents after they used their movement skill.
Follow up with basic attacks and "Made You Look" and never be afraid to activate "Maximum Velocity". "Sonic Boom" is your hail Mary to catch opponents far away, or to get somewhere fast to support your allies.

As for items, you should quickly get to Qin's Sais lvl 3 to get you some decent damage and attack speed. After that focus on your lifesteal with Devourer's Gloves. Max its stacks in between ganks with basic Furies. Then go over to critical hits with Malice and Deathbringer (many people also prefer Golden Bow over Malice).
If you have money to spare lvl up your HoG to FoG, that one second stun can give you at least two hits in late game and every hit is crucial.

The last item is variable, mostly because you never how the enemies develop. Even an enemy team with only one mage can is not a direct indicator to go for armor. You should be able to figure out, which one of your opponents is the most menacing to you and counter his damage a little.

Of course, communication is essential to you being successful with Mercury. Don't force every gank and don't expect everyone to go after you when you initiate (also a reason not to initiate with "Special Delivery").

Be agile, when you attack and run, a basic skill in SMITE, and walk around your enemies. Nothing is more annoying than a fly you can't hit (Muhammad Ali would make a great Mercury player).

Take out the damage dealers first, if that is done go over to the squishy and weak (sometimes its the same) and don't worry about enemies that have gotten away, since there'll always be a second chance to take them down.

Lastly, every character has a different feel and don't be bummed out, if you want to follow this guide, but can't get it all right on your first try. You need to have the patience to learn how your character moves and uses his skills.

I wish you good luck with trying out my guide.
Of course I appreciate commentary to improve it, if nessescary.
