In the build editor you want to check the box marked "Core Items" on the completed build purchase order in order to have the appropriate build show up on the search screen.

Hope I helped :)

Either you go for 9 Greater Mark of Magic Penetration or I suggest you consider Greater Mark of Hybrid Penetration which work great with Clockwork Windup, helps you farming and you don't really have to sacrifice that much Magic Penetration.
Instead of using pictures you can use coding formated by the website like [[Orianna creates Orianna (works also with items, masteries, runes, summoner spells and abilities) and [icon=Orianna size=30] creates (ofc you change the size by changing the number and so you can make the icon bigger).
