Jayce vs Yorick

In cannon form, fire Shock Blast (Q) through Acceleration Gate (E) from the start of lane: the orb gains speed, range and damage, and it's your best poke.

To all-in, switch to hammer: leap in with To the Skies! (Q), activate Lightning Field (W), then knock your target back with Thundering Blow (E).

Land an auto after each weapon swap: switching to Mercury Cannon (R) reduces your target's armor and magic resist, and your first hammer hit deals bonus magic damage.

To escape, swap weapons then walk through Acceleration Gate (E): Hextech Capacitor (passive) and the gate each give you move speed.

Dodge Mourning Mist (E): once marked, you lose armor, his nearby graves keep raising Mist Walkers, and his units rush toward you.

Kill his Mist Walkers, summoned by Shepherd of Souls (passive), before going for him: a single auto or single-target spell is enough for each.

If Dark Procession (W) traps you, hit the wall to break it instead of waiting for it to disappear.

If you can, take down the Maiden of the Mist before Yorick: summoned by Eulogy of the Isles (R), she carries a large part of his damage and push.

Don't let him split push alone: with the Eulogy of the Isles (R) Maiden and his Mist Walkers, he quickly threatens a tower. Send someone to answer him.
