Intro
   The Joker is a collector, his passive gives you more HP with the more coins you collect. With this build you will get the highest Damage/HP/Armor for the least amount of money possible. If you build right and play smart, it's very difficult for an enemy to kill you plus you will have lots of fun killing them in the process.

Skills
Max Q first, it lets you regen while jungling/laning and it does decent damage if you want to engage an enemy. After that max W, keeping your eye on your passive. If you passive reaches it's max HP cap, don't be afraid to add a point in it. Other than that max R at every chance you get and allocate the rest to your E and passive.

- Q - Applies a filth modifier which trigger your R to do more damage than it would on a hero without the modifier. So always smack them with this skill as you go in for the kill. It also deals base damage and gives you some health regen.

- W - toss's a ham that acts as a nuke and a crow control. It's a great initiator as wherever the ham lands on a Hero, the Champion walks in the opposite direction. So if you throw it in front of where they are walking, they will walk backwards to you. Get good at this at you will destroy. Also, keep an eye open for people teleporting in plain site. It helps to use X-Ray stolen power a lot, because people do have a nasty habit of just running into a stealth pad and porting to base. I've killed so many people doing this with a simple ham toss.

- E - Snack time! This skill acts as a skill barrier and a move speed boost all in one. It gives you more movement speed upon activation and then on top of that if an enemy hits you with a skill while it's active you will move even faster. Keep this in mind when running from the enemy or trying to catch up to one. If a joker toss's out his AOE slow or you see Mr. Punchy coming towards you, put this skill up there's no way he can get away from you. Same thing applies if your running away and you sense a batman is about to throw a disc at you, pop this baby up and you will be fine. I think this even blocks NM batmans Ultimate if you time it right.

- R- You rat swarm is very powerful, but be careful with it. It's an AOE damage around your champ with a slow debuff. If a champion get's caught in this after a ham toss there is a high change they are going to die. Just remember to Q them while in this so they take more damage. You can use this skill to kill enemy or if a friend is about to die you can pop this on for a little bit and slow them down. That's assuming you miss you ham toss though. Don't leave this skill on to long because it WILL kill you. Or at the very least drop you low enough to where the enemy can one shot you. This takes some learning before you know your limits.

Do's and Don'ts
Cleaver when possible. It regen's your health and deals a nice flat base damage.

DO NOT leave your ultimate on out of battle. It will drain you to death since it decay's your life while it deals damage. Use it only when your trying to farm clusters of minions, push a lane, or killing an enemy champion. If there's an enemy you are fighting in battle the decline of your HP lessen's.

Use you R selectivly. Only leave it on for a long duration if you are certain you can secure a kill, if not then you are just wasting your health pool. I know it's tempting to leave on a long time since it has a slow, but again only do it if they are getting low and you are certain you will get a kill.

Watch for Snipes. Always be on the lookout for people basing with low HP. It's extra handy to have X-ray for this, but if you catch them out toss a ham and go for the kill. They normally run onto a random stleath pad and do this. I've killed so many people with a simple unexpected ham toss.
