I'm still trying to maintain color symmetry in my cube, however Selesnya is not guild with very many cubeable options. Nature's Chant was just filler because there was nothing better. I just learned about Torsten, Founder of Benalia from the current Magic Online cube. It's a big creature, draws cards, and makes bodies when it dies. Works well with Natural Order, Sneak Attack, Reanimate, or splashing white in a green ramp deck.
