Yeah thats annoying, against miracle you just have to bomb him the second each gas is ready and hope you outrush his shield.
Has anyone looked into improved plague for CCYB? 2
to kill of every enemy creature seems pretty tempting, and it has synergy with the air nymph if you have one. Aflatoxin is pretty damn good, but often it takes too long to draw or afford to play it, and its too late to actually make a major difference. I dunno, I guess it could be something to look into.
