As an inclusion to the deck? I am not sure about a main board but I could see it as a definite side board option to bring in against other Marvel decks. Against the deck, it is great hence why I had to include two Essence Scatters in my side or.
With my current sideboard, some of the spots I feel are flex spots, such as Sigarda,
Glyph Keeper, and
Commit // Memory. Perhaps 3
Spell Queller could take up those spots for an expected heavy Marvel and UW
Flash meta ( or even Zombies).
