Instead of rushing the Longsword into a Manamune, grab a Vamp Scepter instead. It will help your sustain quite a bit. Top lane blitz has, in my opinion, three core early game items:  Vamp Scepter, Tear of the Goddess, and Sheen. From those items you have decent damage and you can follow up with either tankyness, (Iceborne gauntlet, Banshee Veil) or more damage. (Triforce, Hydra)

If you are wondering what ability to max first, the answer is always W.

Blitz has a tough time staying in lane without lifesteal or potions so I almost always bring teleport when playing him top. You can also use Tele to gank bot lane pretty well if your support wards the bush near the enemy tower.
