Outside of stalls, this card is not very powerful. Also, one must consider when this card enters play. I doubt this will ever make it out in the first 3 turns unless it's based off of this. But this usually means that creatures will last through the game before losing immortality. And in most cases, Eternity beats it out in terms of CC.
I was basing the turns on my average games. I can raise the range as 2 does seem a tad small. But knowing RNG, 4~5 turns would pop up more...
