This deck focus on getting the combo ASAP, read my notes below for some advice how you should use your cards and how to get the 7 required  Mogu Cultist

Use Crystology and Salhet's Pride to draw Mogu Cultist, Elven Archer & Helpless Hatchling

Use Elven Archer to kill Helpless Hatchling

Use Helpless Hatchling to makeAugmented Elekk a 2-cost

Use Call to Adventure and Witchwood Piper to draw Baleful Banker

Archmage Vargoth can have many good uses: Crystology, Call to Adventure, Consecration

Duplicating Mogu Cultist:

• Play both Augmented Elekk (1 should cost 2 mana by now)
• Play Mogu Cultist
• Use 2x Baleful Banker on the Mogu Cultist

After that you should have 7 Mogu Cultist in your deck & hand in total.
