For some reason I REALLY don't like this idea... imagine taking down a really powerful creature (say a Pharoh, a Light Dragon, or even a super-buffed Lava Golem with Momentum) and then having the opponent play THIS card in a pinch to revive said powerful creature to get a second chance at owning everything.
Not to mention it's WAY too cheap for its cost. Life could be overdone with this card, if you couple this with the
![Life :life](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/life18x18.png)
Dragons and whatnot. Also: when you play this card, do you have to target a creature (so that upon death, it gets replayed again), or is it automatic (whatever creature goes down, you get it back in your hand)? If it's automatic, I don' know how it's going to work against damage spells like thunderstorm. ???
