This ! made me reach silver,then demoted back to bronze ...since people hates or its not used to meta breaker supports ...and they play on a bad mood or angry a flex good player should be able to win even with this
masteries and items!

items:
or more AP 
AND 
OR 
Edit Note:Gangplank support DOES benefit for masteries passive that grants gold, spellthief dagger and his pistol shot also proc the passive,and if you kill (after item upgrade) you get more gold Gangplank ult also procs the Spellthief ,meaning that if you hit every single enemy with his ultimate you get tons of gold for each!its like 200 or so gold for every one inside ult radius
Shaco shiv also procs spellthief when toss ,but if you kill anything with a box before you upgrade the item it disbales the passive
:) if you have any doubts feel free to contact me or discuss this guide here and my match history doesn't lies,tons of wins with those 2 guys just promoted again using only Support Shaco
I do not mean to be disrespectful but you are talking about braking meta,
yet
you are sumbling on the edge of bronze/silver.
Plus the fact that there is no sightstone included is lowering your credibility as a support player.
I don't like your post
