AD Fizz is an idea I got when thinking about his Q. I first thought that his Q could critically strike. But after doing some research I figured out that his Q couldn't critically strike but I did learn the importance about his W. If you read the tool tip on the W you can see that it works extremely well with BORK.

Marks/Reds: Use either armor pent. or flat AD marks
Glyphs/Blues: Use scaling MR glyphs
Seals/Yellow: Use either scaling Hp or flat armor seals
Quintessence/Purples: Use armor pent. or flat AD quints

You can either run the 21/9/0 mastery page up above or you can run a 9/21/0 page for the extra tankiness. You don't need any points in utility since you are already mobile and with AD Fizz you don''t need much mana.

You want this item. This is one of the biggest reasons AD Fizz is a tank shredder, and since you are going top, you want this. This also makes your ult easier to land with the BORK active.

This is basically an AD version of Lich Bane. Trinity Force works with the W + Q combo on Fizz. This also allows you to stick onto targets.

Even if you are AD Fizz, you still need mana and this is a great source of mana. This item also provides 100 armor and since you want to be tanky, this is a great item for you.

This item is a bit iffy at the moment. You could get a Maw of Malmortius if you wanted the extra AD, but I feel like this makes Fizz tankier so he can survive teamfights.

This is the item that takes your tankiness to a new level and makes you hit just a bit harder. With this item, you can now stick the the carries and now you won't die quickly so after diving the carry and taking them out, you can help the rest of your team.

Q: With AD Fizz, this is the ability that engages/disengages fights or you can stick onto targets with this ability. Your Q is practically a free basic attack.

W: This is your bread-and-butter ability. You'll max out this ability first. This makes your auto-attacks do extra magic damage on-hit and when activated, does damage over time. This damage increases as the target's HP gets lower. This works well with BORK since BORK does more damage when the target has more HP while the W does the opposite. SO when the BORK doesn't do that much more extra damage, the W will become stronger.

E: On AD Fizz, your E is your engage/disengage and is meant to dodge abilities.

R: Since your ult doesn't scale off of AD, your ult is going to be used only for the slow and knock-up that are applied.
