Shirvallah OTK (Rastakhan)

The combo

The goal is to draw your entire deck so that you can play a discounted Shirvallah, the Tiger + Time Out! + Augmented Elekk + Baleful Banker x2, adding enough copies of Shirvallah into your deck so that on your next turn you can Holy Wrath twice to do 50 damage. 

Lowering Shirvallah’s manacost should be fairly easy. Hypothetically, if you have used 2x Flash of Light(4), 2x Potion of Heroism(4),  2x Crystology(4), 2x Consecration(8), and a Shrink Ray(5), Shirvallah will already be down to 0 mana cost.

card choice

2xCrystology – Thins your deck while drawing key cards such as Acolyte of Pain and Bloodmage Thalnos for more card draw, and Stonehill Defender for stalling.

2xFlash of Light – Used to stay alive and cycle while also offering potential to combo with Wild Pyromancer. 

2xShrink Ray – If you need to survive and/or clear the board but don’t have Consecration or Equality, Shrink Ray is another option that can also be played with Wild Pyromancer for a board wipe.

1xA New Challenger... – I think the card will be good enough to warrant at least running one copy. A possible substitution would be adding a copy of Lay on Hands or, if Shirvallah’s mana cost is discounted to 0 consistently enough, a copy of Harrison Jones for more draw.
