I'm worried it would be OP with Singularity and worthless otherwise.
Other use would be AM. Both as a defense against enemy usage and as an emergency heal.
Actually, given the number of times I've lost to Aether decks due to inability to use AM, I think this would actually fit a very amusing niche there.
That said, it may still be a little to situational... The potential for singularity abuse is a fairly big problem too.
