my bad for not testing thoroughly...seems like kami is right
although maybe i am the one who misunderstood what exactly he means by 'as-is'
the term i would use is 'replacement effect'
only Phoenix/Minor Phoenix has a built-in replacement effect that trigger some effects when they die (as other creatures would) but also overwrite aflatoxin death trigger to replace the infected creature with a malignant cell with their own ability, replacing itself with Ash
virus/retrovirus also has a replacement effect, but it only happens when they sacrifice themselves to their ability (devouring or bolting will still leave behind a cell) and thus it is NOT like phoenix/m.phoenix at all
malignant cell on the other hand is a mystery
it doesnt have a replacement effect but, any attempt to get a cell from an aflatoxined cell whether by force (devouring, firebolting etc) or by letting them die will produce no cell, not even a cell created by their own natural ability (but that has been explained in some other thread that i'm too lazy to search right now)
i havent tested what would happen if you tried this with a lobo'ed cell yet though
