Standing Quake is a legendary major card out of the New mechanic pool. Groundbreaker heaves twice: a second upheaval runs the lane 1 s after the first; each slab hits for 45%, no shove.

You can take it once · it only turns up when your Special 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 Fault Line and Twin Fault. Take one and the rest are gone for the run.
