I've been considering moving my Gaiomon deck from a Red base to a Black one, but I just am not a fan of that bottom end. The BT8 Agumon is great, especially the alt-art version, but I prefer the DP+ red Koromon, the black Agumon X is too costly to hardplay, and I just prefer the ST1 Greymon which is an obligate Red digivolve. Wish there were a Red/Black SA+ Greymon, or one with a "2 from Agumon" evolve line.
