Pick a Card is the worst ability to max first. The damage increase doesn't match either Wild Cards or Stacked Deck, and the utility doesn't change past level 1. Though I agree with going AP before AD if you plan on riding hybrid, you should definitely not get two NLRs before your first core item. Max Wild Cards and get a Rabadon, then either Lichbane or Gunblade depending on how much AD you want. Zhonyas is a good item, but don't rush it. Get it late game when team fights are more frequent.

Oh, and your runes are all wrong. Stacking one stat on every type of rune is extremely inefficient. You should replace your marks with Magic Pen and glyphs with either Magic Resist or Mana Regen per 5.

Not the most regular build, but I feel like it does have the potential to deal massive damage. Some hybrid items you might want to give a try: Guinsoo's Rageblade, Lich Bane or Hextech Gunblade.

About the guide, I do feel like it is a bit to much text for the amount of pictures you are using. Try making it look more flashy and more ppl will read the whole thing.

Nice, Long story ;) jkk! but really... nice build. Its kinda hard to get those NLR tho... but other than that gj! +1

Dude This looks SWEET! I'm going to try it out!!

EDIT:

I MOPPED UP!! 36 assists! some suggestions tho... Put some mana in there dude! i know the blue card gives mana but I think you could put mana in there and still retain enough attack damage and ability power.. other than that, Awesome build!
