Singularity is a legendary major card out of the New mechanic pool. Spirit Burst drags everything within 11.8 u into you, then bursts for 80% over 7.8 u with no shove.

You can take it once · it only turns up when your Ultimate ability can actually use it · it can be offered for 0 of the 34 abilities.

Only one card can reshape that ability this way — this one, or Supernova and Scorched Ring. Take one and the rest are gone for the run.
