Not that sad, really, I only ever use radiation as surprise ranged finishers on priests. I think that I'd rather see more counters to Walpurgis night than see the radiation pool maintain its quality. After all, it already has Festering guts in it, which is really a pretty awesome card. Any person who uses radiation a lot probably won't mind the extra forms, as it will just add to their RNG lifestyle. Radiation is already a very variable strategy that can potentially be game changing in your enemy's favor, while gene therapy and lateral thinking are currently cards designed to deal with unwanted traits being attached to you. They should have the power to deal with these new unwanted traits. Also, as I have enumerated before, I believe Ethereal form is bad because their cards pack hardly any damage, and it would be a worthwhile thing if radiation attached it to the enemy.
