So this is my first build I've done. I think it works pretty well in every situation, based on new players who aren't so commen with League of Legends. So basicly you just try to make some trade with Q against lane opponent(s), go for the kill @ level 4 when you get ur E to level 2. ROAM ONLY IF YOU OPPONENT ROAMS TOO!

Runes can be mixed little, basicly armor + magic resist is correct, but Marks can be changed to

Very basic you can also use tier 2 runes if you arent that high level yet, or if you just don't want to waste that much IP for runes.

If your team is being nice etc, and they are giving you blue buffs you don't need morellonicom at all. You can just replace it with Zhonya's Hourglass or Guardian Angel. For saving yourself in team fights more easily. If enemy team has jungler and you have some extra money after buying new items you can always buy some wards, they aren't waste of gold at all, never!
