Looks a little heavy on the air. Might want to take out the unstable gas (if you find that the wyrm sucks all air quanta).
I also find that instead of a vampire, use a liquid shadow. This helps with EM because in the lategame you can LS hugh growth creatures, or save yourself from dying. Yoiu can also make sure that your LS'd creature attacks first (just in case you want EM, this helps because the LS'd creature will attack before your creatures kill the person.)
I'm suprised not to see a forest spectre in there, (helps to have another creature with growth when packing a Liquid shadow.
