Monks are a creature type appearing across several colors and strategies, with many tied to prowess, noncreature spells, or disciplined combat. They lack one universal typal mechanic but have numerous individually strong build-arounds.
Jeskai Ascendancy fits naturally beside spell-focused Monks, while Ojutai Exemplars turns each noncreature spell into a choice of combat abilities. Elsha of the Infinite pushes the theme toward casting noncreature spells from the top of your library.
