A word of caution regarding archetypes in GU Decks: the archetype rules are set by a player (jazus) on behalf of the GU Decks team and they are in dire need of updating. On top of that, if you add Necrocepter it's very likely a 'midrange deck' without many Dragons or Dreads would be classified immediately as 'Zombies'. I would look at all archetype designations with a critical eye. Many are almost meaningless.

That deck you shared from matrix13 has some really questionable choices, like Scalecult Conscript without any Dread generation and On Her Command, which is a super expensive single-target removal with an upside that is very difficult to hit with the only 1-mana Anubians coming from Heirlooms, which frankly get removed 95% of the times during the opponent's turn. The card is not played in a full-on Anubian / Heirloom deck, so in a deck like this it makes even less sense. Harrowing Visions and Reclaim are 2 expensive draw cards, Death has much better options than these. A deck like this usually cannot afford to spend 1 turn just drawing cards and not putting any meaningful pressure on the board. Blood Armor is almost useless and Blight Bomb would be a much better card for that 1 mana slot. Curse of Greed is much better than Vengeful Surrepite, Bronze Servant (Anubian!) instead of Basilisk, etc. There are some obvious substitutions to be made to that list and even then I'm not sure it would compete in Solar+.
