While experimenting with decks including Expired Merchant and Soulwarden, we had several amazing games. One of the games included summoning multiple Dragonqueen Alexstraszas (4 in one game), and another led to us getting extra Grand Lackey Erkhs.

Basically, if you ensure that the highest cost card in your hand is one you want to duplicate, you can get multiples of it. It is recommended you use a card to kill it immediately in case your opponent has silence of some sort.  Once you have the card you like in the discard pool, you can get 2 more copies (or 4 more if you used both Expired Merchants on it) over the course of the game with Soulwarden. Pretty much all the games with this deck have been a blast! Let us know in the comments below if you end up trying this deck out!

We had so much fun and unique/interesting games with this, we actually ended up making 3 play-through videos. They can be found here: https://youtu.be/_7Fo-FViE9A for part 1, https://youtu.be/wEoG2pzCEpQ for part 2, and part 3 is at https://youtu.be/UjGtfXyZre4.

Thanks for checking it out!
