Fun idea for reaching 20 artifacts on your own.IDK, he's not giving me actual card advantage there...
I'm thinking about putting more artifacts in there/replacing the non-permanents, for those times when I need to reach 20+ artifacts on my own... Temple Bell, or something.
Selective memory to get rid of non permanent cards from your deck then add green for Primal surge to draw 20 artifacts and put them into play.
