Pyke

Strengths

Pyke is very fragile so don't be afraid to temporarily run from a fight. You can regenerate a significant amount of health from Gift of the Drowned Ones when enemies can't see you.
Hitting an enemy with the Hold version of Bone Skewer will always pull them the same distance. Use it in melee range to throw targets behind you.
The Tap version of Bone Skewer is much faster and deals additional damage.

Passive · Gift of the Drowned Ones — When Pyke is hidden from enemies, he regenerates damage that he has recently taken from champions. Pyke also cannot gain extra Maximum Health from any source, and instead gains Bonus AD.
Q · Bone Skewer — Pyke either stabs an enemy in front of him or pulls an enemy towards him.
W · Ghostwater Dive — Pyke enters Camouflage and gains significant Move Speed that decays over time.
E · Phantom Undertow — Pyke dashes and leaves behind a phantom that will return to him, stunning enemy champions along its path.
Ultimate · Death From Below — Pyke blinks to and executes low health enemies, allowing him to cast this spell again and granting additional gold to an ally who assists.

A suggested 5-lane lineup built around Pyke, based on hero partnerships and role synergy — not win rate.
