Hmm, so if you devor something that creature gets a virus. Seems to negate half the purpose of devoring anything, or do you mean a certain creature that when devored give the other creature a virus, that makes much more sense.
I don't even get your second example.
Also, shouldn't this be in the feature request thread?
It would be cool to have card that have effects when they come into play, like the upgraded towers, but have a different ability than the one they activate by comeing into play. (That reminds me, look at the splash tower thread)
