Passive: Shepherd of Souls- Yorick can have up to four Mist Walkers in his service at once. Mist Walkers instantly die if they move too far from either Yorick or the Maiden of the Mist. A grave is occasionally created when enemy minions or neutral monsters die near Yorick, and all enemy champions that die near him leave a grave.
Q: Last Rites and Awakening- Yorick's next basic attack deals bonus damage and restores some health. If Last Rites kills a target, it creates a grave. If there are at least three graves nearby and Last Rites is on cooldown, Yorick can instead cast Awakening to raise Mist Walkers from the graves.
W: Dark Procession- Yorick summons a destructible wall of corpses that encircles a target area for a few seconds.
E: Mourning Mist- Yorick hurls a globule of Mist that deals magic damage, applies a slow, and marks a target. Yorick and Mist Walkers get a movement bonus when heading toward marked targets.
R: Eulogy of the Isles- Yorick summons the Maiden of the Mist (at higher ranks, she'll bring some Mist Walkers with her). The Maiden moves and attacks on her own. When Yorick attacks the Maiden's target, he'll deal bonus magic damage based on the enemy's maximum health.

Yorick is jaggernaut, so he can build off tank, sometimes full tank and he can still deal so mutch dmg. In teamfights he is in front line and with his teleport he can use his great split potencial.

You can activate his ult when your minions are pushing top tower, let your ult push too with her ghouls and you can teleport on botline and push with your teammates. With this tactic you can push two towers at the same time.

Notes for runes and masteries and some vidios will be updated early ;)
