Oh damn, thanks for pointing that out. I mistaken Subutai with his son Uryanhakdai who was also said to be present during the Kalka River battle. While Kublai Khan did conquer Northern China, that's just one of the only a few campaigns which he accomplished. China and the Civil War were just one thing, but his failures in his future campaigns after that outweights what he accomplised, for me anyways. One can argue that it was either rotten bad luck or stupid insight why he lost Japan, but he did made some pretty costly and dumb decisions during his Vietnam and Java campaigns.
