Hello, welcome to my tf build/guide, really really sorry if the guide looks sloppy I am not good at the tools they provide so please don't be B5 cruel to me.

The pros

to this build is that he scales quite well
takes a little practice
not super reliant on blue
his ganks are super easy
has an engage with hourglass + yellow card + ult
can kite well
can level 2/3 gank well
utility doesn't fall off even when behind
ult is game changing/free vision

The cons

super easy to counter jungle if team doesn't help
damage can fall off if behind
might get flamed for off meta pick

When in the jungle especially when you make your first clear it is 100% important to start on krugs smite and use gold card as much as possible gold card is this guys bread and butter of jungling, ganking, escaping, pretty much anything but fast clearing and mana sustain.

If a lane is pushed ping that you are coming in, you/they can engage as your stun sets up for an easy cc chain.

On dragon or baron, spam blue card as it does the most base damage, and if you are stealing just gold card the jungler get them to stop focusing dragon, set up blue card, use wild card blue card smite burst for easy steal.

Before the fight spam wild card at a level to where they hurt and you keep your mana above 50%

When the fight starts gold card any tanks that get close, gold card any assassins that get close, pretty much gold anything that does anything except tebbers please don't be that guy.

Once the team fight is ending you can use your ult for a quick escape if you have the time or to catch a fleeing meal. (ult + ready gold card + ult to them = yummy 300g)

To sum everything up I think he is a fun jungler and can defiantly fit into a ranked game if you need an ap damage jungler that doesn't fall off and can gank well.
