'Tigger, never say never!  I in fact HAVE successfully run an all Blaster/Burrower army, and even an all Blister army.  The first won two out of three, and the second won the only game it was in.  We were re-creating the Tophet campaign from the TV series and decided to give this army a try.  The biggest things I can tell you would be to use swarming to your advantage, use your reinforcements wisely, and DO NOT sit still!  It's a challenge, but it can work (only a couple times though :lol: )!
