Making the Promo Work - Know When to Hold 'em

The first of two theorycrafting builds for this week: Know When to Hold 'em presents a challenge. It's Linrei's Kiss for 1 cost with a heavy time restriction. Linrei's Kiss isn't played much that I'm aware of, because even with the cost reduction it's a very large price to pay for getting the one card you need. So how does this work at 1 mana at slow speed?

The answer is fate. Using this spell-heavy mono-Primal midrange deck based around Mokhnati, Restored and Prodigious Sorcery, the new promo has a special place of creating snowballs whenever we need them by fetching Jotun Hurler, then burying the Jotun with either Primal Etchings, Strategize, or Jennev Merchant.

7/23 Update:
All copies are unlocked and testing has gone pretty well so far. The final build includes Mistveil Drake as a one-of for when you need aegis. If you can hold onto the face aegis for five turns (completely feasible), the drake turns into quite a beatstick.
