[Shadows of the Spire] The Swap

This deck is all about making the most of Spire Shadows which is lots of fun.
We have 10 merchants simply to make sure we get to play this card turn 4. Ever creature in your hand before you play The Swap is less cost effective than after.

Still messing around with what's good and what's not.
Dizo, Cabal Racketeer and Sandspout Mirage were there for a while, but felt pretty niche.

What else would be fun in this format? Let me know your thoughts!
