I'm confused about your item section:

1. Match Ups:
You have an Iceborn Gauntlet icon there, but in the notes you say "VS AD tiamat/ninja tabi, VS AP hex drinker/merc treads"
2. Choose One (Notes):
Do you mean to say Frozen Mallet or Frozen Heart, not "Frozen Gauntlet" -(which doesn't exist)-? Or are you actually referring to the Iceborn Gauntlet you have in the icons section?

Plz clear these up :)

I just don't like the Hextech Gunblade purchase added to what you're suggesting to build. It can be a niche pick later on and it seems like offering some synergy but I'm still doubting its strength. Besides, you won't likely build IbG against AD as you will follow a normal build most of the time. The benefits of this item are small because your sticking power is decent and you just lickely want to get the spellblade-procs > Triforce < this one isn't worth at all, too. Stats like armor can be gained by items like Randuin's Omen which also provides health to back up the armor.
Hexdrinker is fine in lane but you will just upgrade it in the late game to MoM.
I dislike the Runes because often flat Runes are more valuable than scaling ones like the flat magic resist runes. Instead of scaling AD seals there are more suitable options like flat or scaling health and armor.
Enchanted Armor is mathematically worthless.
