 Evocation is a natural fit and costs 0 mana with Sorcerer's Apprentice. Furthermore she discounts the random spells in your hand obtained from evoquation. This will make completing he quest even sooner and easier.

Maiev Shadowsong will be a neutral legendary that will be auto-included in every deck. She is just way to good. Whether it's bypassing a taunt minion or disarming a must answer threat.

Last but certainly not least is Astromancer Solarian in his basic form of 2 mana he provides spell damage +1 to all your little spells like Arcane Breath and Ray of Frost. His prime form is a mini Yogg with the upside it only targets enemy minions. What more can you ask ?

The sad truth is that even tough i want to believe this deck to be good i can't see it. Reno Lock without specific tech vs the current meta consisting of quest reno mage or quest tempo mage, both sill being S tier decks, gets preyed upon by these decks. Your only hope is not to be matched against them. Even unnerfed raza priest is an easy win for those  mage decks.

Cube lock with albatross would do a lot better against them since it's more consistent and faster then the highlander variant. Can you do well with reno lock ? Yes in a vacuum  where you encounter almost no mages. Loatheb and unseen saboteur being absent from this list is a big mistake in my book.

Basically the scry effect of mtg but on steroids since you can look at 3 cards instead of the 2 in mtg. This card is game changing in a lot of ways.
