This Champion is easy too play. Be carefull with his Health he doesn't have much. He also will be better when he has all his items. In begin be more defensive. But do aid your team of they go on the attack but don't run to far (even in end game)

Stack on Crit and Cooldown reduction Runes

At endgame sell one avarice blade and make that a phantom dancer or a last whisper if enemy targets are tanks.

First Skill= Range DMG (Try to make the kills with it, it will give bonus money then)
Second Skill= Health Restore but prior is to get out of all Crowd Control Effect. Such as Ashes' Frozen arrow.
Third Skill= Use to run away or to help team to attack. Can also be used to get more DMG for sometime.
Last Skill= It doesn't do much DMG but it's nice to use it for slow effect. It is useable all over the map so if you see a team mate being chased then use your ulti behind him to try to safe him.

Pros:
-Powerfull DMG
-Fast Money Farm
-Possible Supporter

Cons:
-Quickly dies
-Only crits mostly endgame

Stay back and use first skill to finish of the minions.

Team should always try to rescue Gangplank and if possible gangplank needs to come back to aid for the kill.
