This gangplank stays in lane and should not lose in it. The longsword and mana potion give you the mana and damage to deny minions and parlay/ smite a ton. Starting the game with 2 less minions is a major advantage not only by levels, but by the ability to play defensively. at level 6 recall and buy the Sword of occult and boots of swiftness and look for a lane to ultimate while you stand in base and get a free or 2 free occult charges. Once you have around 2,000 gold go back and buy a sheen and avarice for the extra crit, crit damage, and gold. The heal is crutial to get at least level 1 to cleanse stuns that lead to gank, and most of all staying in lane. Now that you have been killing and farming you should have around 4080 and 6-8 occult charges. Recall and buy your Infinity Edge. By now the killing should be easy. 10-14 occult charges and get Bloodthirster and finish your Ghostblade. If the game isn't over already it should be. Finish your Trinity Force giving the added slow on parlay, MS, Health, Mana, AD and AP needed to finish the game.

Pros:
Excellent Farmer and possible neutraller, i have not tried.
Tons of damage for crit
MS to catch anyone

Cons:
No surviveability
Farming can only get you so far. End game is all skill, recommend trade ghost blade for 2nd Bloodthirster and occult for 3rd or GA, if you are not getting charges.
Mana regeneration early. But if you are good enough you can get blue buff and it will not matter.
