Losing 4 life (or even 2 life, really) to kill one of Zoo's creatures = frownie face, since all their shit fulfills the same function of dealing damage to your dome quickly, and you've just helped them with that proposition. Also, for the record we've basically already had this option with Snuff Out, albeit that card actually requires a true black splash and has different target-ability requirements. But I still think Dismember just won't work in Merfolk.
