Hi! I love Mardu colors, and I'm happy to see other people building into them. I like the idea of building an
Eldrazi Displacer deck in Mardu, as it gives access to so many great cards. I was wondering if you thought about Tidehollow Skuller as a replacement for
Brain Maggot. It's still in your colors, has a bigger body, and since it's a zombie, Kalitas can eat him once you displace the exiled card. Just something to think about. Good luck!
