Overview

This is a fun deck (not for laddering at higher levels) built around utilizing The Fast Lane.

Basic Strategy

Play Stubborn Tengu. Bounce him back with Stratagem Thirty-Six. Now Stubborn Tengu only costs 0 mana and 1 purple gem, and that cost reduction is permanent. Repeatedly play him with The Fast Lane or Dashing Ringmaster to do a lot of damage, build up a lot of Souls for your Journey of Souls path, or trigger other cards that benefit from your minions dying, like Red Carnival or The Oak of Dodona. Ideally you only burn 2 or 3 red gems, and the rest purple, since you want to be able to play Tengu as many times as possible for 0 mana.

Replacements

I highly recommend running a second Dashing Ringmaster as well as Sea Lord's Trident. The only reason I didn't include those cards is that I don't own them. There are many red cards that benefit from Tengu deaths, such as Dead Man's Eyes and Enyo, Murder's Muse, which I did not include. You can try running them, but keep in mind that you want to have a lot of purple gems to play Tengu as many times as possible, so don't overdo it too much on the red. In particular, Melinöe, Soul Shephard does not work with this strategy, since her Forlorn Spirits each cost a red gem, and you can't play them fast enough for each purple gem you spend to make them.

Most of the cards outside of the core combo (Tengu, Stratagem, Fast Lane) are replaceable, so I would experiment and see what works for you.
