Note: Gravity Shield unfortunately blocks antimattered creatures with over 5 hp.
it doesn't, have you tried it?
Hmm I just tried it in a different game and it did block the healing this time...
Looks like there might be a bug somewhere as I'm 100% sure it does work somestime. No idea what criteria are involved though...
Also taken your suggestions on board and updated the first post to give the new version of what I'm palying with. I appreciate the joys of a 30 card deck but were having some serious problems getting any towers at all so felt I had to boost it a little bit over that. It's still smaller than my original 38 cards which is good though.
