A Whole Month of Spooky Gangplank

A lot has happened this month for me:GP jung soloing dragon,GP top 1 shotting the enemy tank,mid lane GP coining a build I'd like to call 'Zed Smasher',and Support GP winning Lv.3 all ins.Honestly I don't know how I have survived this month so far,but I have played GP in literally every position with decent enough results.And while its fun and all I don't think I'll be playing GP again for a very long time after the 31st of this month lol What are some builds you all think I should do before it ends?Any suggestions and I'll likely do it :)
