Hi everyone! Thanks for clicking on my Gangplank guide! In this guide, I'll go over Gangplank's strengths and weaknesses, his matchups, items, runes, summoner spells, and just how to play him in general. As a champion, Gangplank is a melee top laner/mid laner, but this guide will focus on him as a top laner.

CritPlank Runes:
Kleptomancy is a great rune for Gangplank. His Q, Parrrley activates Kleptomancy by itself, and it generally fits into his champion identity as an extra source of gold income and sustain.
Magical Footwear gives you free boots at 10 minutes, but you can't buy boots before then.
Perfect Timing gives you a 1-time Zhonya's at 10 minutes which also works as a discount for Guardian Angel.
Biscuit Delivery is really nice for early laning. Not only does it give a hefty amount of healing, but it also gives permanent maximum mana, which is great for laning.
Future's Market is an interesting rune. It works really well with Gangplank because it means you can hit your powerspikes earlier.
Cosmic Insight raises the CDR cap and gives extra CDR on basically everything.
Time Warp Tonic gives your potions more oomph and some movement speed when you pop them.

Sorcery secondary:
Celerity makes you go a little faster and gives you extra damage for being fast, it's a pretty good choice for full damage.
Gathering Storm makes you scale infinitely.
Transcendence gives you 10% CDR when you reach level 10, and gives you bonus AD for surpassing the CDR cap.
Manaflow Band gives you a free ability cast every so often and refunds mana along with it.
