I'm starting to use this build. I noticed that I can now successfully do MASSIVE damage. This build is extremely good, almost perfect. The only I didn't really is the megias. Not much point into the item. So long story short, I use this build expect for the megias, I use the rylai's crystal thingy stuff, cuz it gives me 500 health (which is a decent amount) and ability power. Overall, nice job.

Fizz can have a lot of damage output if you choose plain ap runes and magic Pen. AS soon as you hit lvl 2 just use your W+Q combo and you have much more damge output than most of champs at this level try it and you'll see

I dont think buying mejais that late in game is senseful, the rest of the items is more or less usual and there is nothing special about it.

Yeah it's my first build and I do need to update it And fix it but I don't use archangels I use megias but this build works great for me and thanks for the feed back but I'm just posting what I use and I love this build and I use it in ranked games so I'm not adding what other people want I'm just adding it so if it works for somone than great

Dude make sure you got permission for your vids...
overall the build needs some work, keep working at it and you will do fine.
