Mordikaar has had one of the harshest receptions since the opening of the Field Test. And not without some justification on our part. He is to unfocused with a variety of spells that, while interesting, are ultimately to expensive or to limited in their application. He needs a clarity of purpose, a clearly defined means of obtaining victory. Which is not to say he needs to fall into the one trick pony trap that plagued MKI. Rather his rules should all flow from his central premis: A scholar with a connection to the void that allows him to defy death itself.
With that in mind here are some changes I suggest for Mordikaar.
Give him a +1 RAT and a +1 ROF for Death Blast.
Let him turn a destroyed living Skorne warrior into a Void Spirit, once per game.
Drop these three spells: Death Sentence, Essence Blast, and Void Gate.
Replace them with Ashen Veil (from The Testemant), Hollow (from Zaal), and Refuge (from Epic Doomshaper)
Here is my reasoning.
The RAT and ROF increase is because, with these changes, he has no offensive spells. He is a scholar remember, not a warrior. However, he really doesn't need them with these increases, which opens his spell list up for more support spells.
The turn a dead Skorne into a Void Spirit bit is to help solidify his connections to that model, while giving him an unperdictable element. He needed a bit more of both.
We drop Death Sentence for Hollow because he doesn't want to be that exposed to cast an offensive upkeep, and Hollow helps keep his units together without any of the inherent contradictions we find with Zaal having it.
We drop Essence Blast for Ashen Veil because Essence Blast doesn't fit with this design, much as I would have loved to keep it. While Ashen Veil makes his stuff harder to hit, up close or at a distance.
We drop Void Gate for Refuege because Void Gate is way to pricey for what it does, and Mordikaar would rather be casting Ghost Walk or Revive with that fury. Refuege, however, helps protect his stuff from reprisals while also grant a mobility buff which is a major theme for Skorne in MKII
Everything else stays as is.
I think these change will solidify him as a premiere support focused warlock that makes sure his army out lasts the other guys so they can do the killing for him.
So how about it, would you play him?
