The gameplan of this deck is to give two Krulls lifesteal with Xenan Lifespeaker, get Means to an End into play, and dump your deck in one turn while chain resurrecting merchants. Each merchant swaps a lifesteal Krull in your hand with one in your market, which mills some cards with Means to an End while returning another merchant with Krull's fate. Once your board is full, you can sacrifice merchants to board space, which guaranteed you'll empty your deck. If Means to an End isn't enough to end the game (over 25 health or face aegis), Xenan Fanatic will finish the job.
If Whispering Wind is allowed to survive, it can enable the full combo in a few turns - discarding a merchant will always draw Krull, which will put the merchant back into play, sending the Krull to the market and pulling a combo piece. If you can mill a Krull with Vines or Sporefolk, Last Chance in the maindeck and Dark Return in the market can get it out with power left to return a merchant. Remembrance in the market is there to start the combo by replaying a merchant with almost all your power open.
Unfortunately, this combo doesn't work in ranked because the timer keeps ticking down even though you're playing cards.
