The AI should learn to count healing before using SoSa.
In one arena game the AI used a SoSa, then I generated a singularity and TUd it, at the end of the turn one of the singularities TUd itself. The healing was higher than the damage, yet the AI kept spamming SoSas and eventually died.
In a different game I had SoSa in my deck, the AI had several SoGs in play. It mindgated a SoSa, used it and got killed by its own SoGs.
