That's a pretty cool idea, but I think the two effects have poor synergy. You -want- this creature to die most of the time, especially the upped one, and fire cards often help this process take place. The beneficial death effect essentially gives it immunity to fire cards anyway (and several cards from other elements) because nobody will want to kill it very often. Depending on your creativity, I'd take the protection from fire ability and put that on one card, and use the death effect for another card, and rework this one slightly. Keep the ideas though; both are good, they just don't fit well together, kind of like a Spark with devour ability. (which fallen druid gave me once...)
