Why Yuumi JG?

Obviously the main reason for this is having fun, please just don't play it on ranked. However, if one or two of your teammates gets fed in the early game, you and the support can help him to get even more fed in the mid-late game since that's what this champion must do from the jungle, be another support (like Ivern does for example).

In which ranks is this strat viable?

In my experience, between Iron and Gold level players usually underestimate you and also don't know how to act when they're getting invaded. Above Gold, it gets more complicated, so I'd recommend you to use a smurf if you wanna play this champion in the Jungle and your main is above Gold

Team Composition

First of all, try to play this when you're a premade team, though with 2 friends that play in the bot lane is enough. The support should have preferably a hook like Thresh, Pyke, Blitzcrank, or Nautilus, or a stun like Morgana or Swain. The top laner should have a good level 1 like Mordekaiser, Garen or Sett, and the mid laner should preferably have a good level 1 aswell like Twisted Fate for example, however, it's not necessary. Finally, your Adc should use a champ that he usually uses in that position, or an Adc with great sustain and wave clearing, you'll see why later.

Invade

You wanna start the game with an invade through the bot lane, it doesn't matter if you're from the red or blue side, if you win the invade, then upgrade Zoomies (E) and ask the bot lane to tank the first buff (It's much easier if you're premade with them) while you heal them, try not to use the Smite in that buff, don't be stingy though, if you see that it can be stolen from you just smite it. Then upgrade Prowling Projectile (Q) and go back to your jungle, you can do the next buff without using either Heal or Smite, however, if you didn't use the Smite during the invade use it here to finish it quicker. After this, the Scuttle probably appeared so you should try to get it, with Waterwalking you'll do it faster than you normally do, so right after you finish it go to the other Scuttle and try to get that one as well, if you succeed and the enemy jungler didn't steal your top lane buff then you should take it and do either the Gromp/ Krugs aswell.

If everything mentioned above went correctly then you can either back to your base or try to gank mid (If mid is too pushed you can go to bot), if you have Exhaust this is pretty easy, however, if you don't then tell your teammate to start trading, and when the enemy thinks he'll win you walk in and heal your ally with Zoomies if your ganks to any of those lanes succeed you can try to take Drake (Obviously with the help of your teammate/s), if they don't just back and buy Stalker's Blade and/or Chalice of Harmony).

Now is why you should be premade with your bot lane, to gank lanes you'll gank bot lane and try to push the wave as much as you can, then ask your support to roam, you'll get on him ( You and Me!) and go to gank mid, this is why you preferably want a support with great mobility and hooks, when you get there simply try to hit the enemy with Prowling Projectile and heal your mid laner with Zoomies. To gank Top lane both of you (The support and you) have to back and go to top lane from base. If the gank succeeds (It probably will since it's a 3v1) then try to do the Rift Herald or gank mid, then you can clear your camps and he can go back to the bot lane.

In the mid-game you'll focus on doing objectives like Drakes and Rift Heralds while being with your team to support them as much as possible, farming becomes a secondary thing in this stage of the game. If your mid-game goes really well you can even think about replacing Redemption for Mejai's Soulstealer or even Rabadon's Deathcap if you have enough gold.

Stealing objectives

Yuumi is a really bad champion to steal objectives with since she doesn't have Flash or any ability to cross walls, adding to that she is really squishy so they can kill you before you even smite the monster. Your best option is to get on a champion with the ability to cross walls or Flash and smite it from there (Even though if you're trying to steal a Baron 2 of you may lose it, it's still worth it)

Here you have one of the many games that I won as Yuumi JG, it's not a tight game or anything like that, it's just a proof of what a Yuumi jungle can do if their teammates do everything correctly.
