Can yall tell me how this build looks?
Start with cloth armor and 5 hp pots. Save/build Phage and then Ninja Tabi Boots. Then Giants belt and later Vampiric Sceptor. Then Frozen mallet and then BF sword. Get BT next. Then get/build Hexdrinker and Maw of malmortiius. Build Guardian Angel. The last item is optional depending on whether you need to be more tanky or more damager.
As for runes, I just use Quintessence of Desolation for Armor penetration, Mark of Alacrity for some AS, Seal of Resilience for some extra armor, and glyph of shielding for some MR. For masteries, I'm currently using:

Ultimately going for:

So, is this build ok? What , if any, can I do to improve this build? Constructive criticism is appreciated.
