You basicly roam alot to get ultimate hunter stacks. You get back to lane pretty quick with mobility boots and w.
Predator is in my eyes the best rune for pyke, you channel when you are still in w. Nimbus cloak is damn good on him too. I had the most success with using the hook, not to engage, but to get someone back into a fight. This says that you should engage with predator in w, and then e out of the w for a stun.

Try to get people from bushes, whether with your hook or your stundash, it doesnt really matter, but you cant use your hook to get people back in your face, when you strait up hook them to engage.

The only thing that really looks wierd on him is essence reaver, but as your abillities are expansive you have mana problems quite often, essence reaver fixes this and the problem that the cooldowns are quite high.
