Hybrid Malzahar

As I've mentioned before, I keep a running list of "things I'd like to try". The newest entry on that list is "Hybrid Malzahar". The idea came to me when I discovered Banner of Command is a percent damage boosting item and Malzahar's pets scale off of AD.

A build that looks like this would be really interesting and fun, I think.

Ionian Boots of Lucidity (Captain)
Hextech Gunblade
Guinsoo's Rageblade
Iceborn Gauntlet
Banner of Command
Manamune

You generate AD of 200+ (depending on runes and masteries) which translates into voidlings doing 300 damage per hit. That's actually very good. The voidlings are somewhat easily controlled with Malefic Visions. You'd have to do the math to figure out whether you're doing more total damage but it's relatively easy for Malzahar to get two Voidlings out during a team fight (lead into the fight with 3 spell stacks of your passive, then cast Malefic Visions, Null Zone, Call of the Void, Nether Grasp and Ignite/Gunblade/Promote or wait for another Malefic Visions. There are some very real challenges with this build.

1) You're squishy as all hell. Iceborn Gauntlet gives you some armor and Hextech gives you some sustain but you're still pretty vulnerable. The plus side is that someone who rushes Blade of the Ruined King will being doing squat for damage to you. AP champs are going to crush you.
2) You're not particularly effective at split pushing due to not having an escape. This is somewhat mititgated by your pets which provide a real nuisance to anyone chasing you. But you're no Shen. Still, Banner of Command means your minions will be hitting people hard so if they try to send a support or non-tanky character to harass you away, you can still get a kill.
3) You don't really hit a critical mass until you get most of the items. You have to rush Banner of Command to get the most out of it but that leaves you somewhat ineffectual while you build the pieces.
4) It's expensive. The full build costs 15,610 and because of #3 above, you're probably not going to be doing crazy damage until later.
5) You're going to go OOM REALLY quick with the Muramana active on. I don't know how it interacts with Malefic Visions but at 3% per single target spell and per attack, you're going to be chunking through it quick. That's okay though because your alpha at the beginning of the fight will be insane and when your mana gets lower, you go ahead and ult to finish someone else off.
6) Auto-attacking isn't conducive to your channeled ult.

The ideal opponent comp would be AD tanky bruisers (Vi, Kha-Zix, etc) with limited mobility and an ADC who's going to rush Blade of the Ruined King (Tristana). It's a fairly niche composition but one that will still get punished severely by this build (I think).

I'm going to try it tonight against bots and intentionally farm slowly to try to get to full build (or close to it). It may not be good. But it'll sure be fun.
