With Yorick being on sale I suggest you'd buy the Gravedigger

He's actually quite enjoyable, if you're not on the receiving end of his shovel.

Try playing him Jungle though, he's really damn fun. Your Jungle sustain is insane and you can actually solo Dragon at around level 4-6 if you do it correctly and you won't even lose any health.

With a build like this you'll be damn near unkillable and provide a lot of utility to your team due to you having 40% CDR, making you a monstrous drain tank who slows enemies 24/7, speeds himself up and revives fallen teammates.

So if you have any spare Rp or Ip for that matter pick up Yorick and make them remember yorick mori.
