Tormod seems interesting, if underpowered, but than again, all partners should be underpowered, because you do get two. Looking at the various potential partners, the only one I found fun enough is [scryfall]Ghost of Ramirez DePietro[/scryfall], another underpowered commander. I do also like how Ghost enables a certain amount of diplomacy, even if that is kind of hard to utilize.
WHat to do with this pair? Madness? I guess it doesn’t actually work due to the new rules. Delve? That’s are handily largely in blue and black. Both also have plenty of self-mill and cycling, which are helpful.
