I did something similar here

fumigate. It doesn't really populate additional creatures to embalm kwhich, with the exception of hobored hydra, tends to cost more, not less) and
fumigate would kill off already embalmed creatures entirely. Blue in place of red gives you draw and discard effects as well as extra embalming options.
