Mad scientist, before mad scientist was a thing

Cool moves!

Although I'm still extremely confused you keep saying mad scientist multiple times in the video but there's no secrets and no mad scientists, or is there a joke I'm missing?

Explanation: youtube video is called "secret mad scientist priest deck revealed" and was made a long time ago. It actually features crazed scientist, not mad scientist, and secret refers to the fact that nobody knows about it, not that it actually uses secrets

I love this deck, I used to play it a lot before I had legendaries of my own :)

before mad scientist existed
