Another card with a good idea by FAR too situational, like Purify but with Devour. Devour is more widely used but its still specifically targeting this one ability.
The ability of infecting something that devour the Worm is situational, but the ability of splitting and kepping the attack isn't.And, know that I thought, I think that is impossible to have two passive abilities.
I appreciate this card for the fact that it unravels quite a few new strategies as it is multi-purpose in nature. Just a question though if I cast aflatoxin on it, does that mean it will start splitting even before it turns into a malignant cell? And does it then turn into 4 malignant cells?? Because I have a lot of diabolical ways of exploiting that XD
