The idea is a soft protection against mass CC to complement the low HP of most fire creatures. This may be too strong in-element, so could easily be converted into an card. Alternatively, it could be reflavoured completely to go with another element - say, unstable goo, or a graviton mine. The exact damage numbers are loosely inspired by the ghost of the past and time bomb damage abilities, and could (probably should) also be tweaked for balance.

Neat idea.

I feel like Voodoo Doll and Martyr were supposed to fill that niche, but I'm not sure those have strong enough effects.

For your version to be really effective, you'd want some way to spam potatoes -- just like you want an Air Nymph to make Unstable Gas, you'd want a way to nurture enough potatoes to kill your opponent, probably with your own CC.
