Knife Storm is a legendary major card out of the New mechanic pool. Knife Toss throws 3 knives in a 30° fan at 55% damage each.

You can take it once · it only turns up when your Main 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 Ricochet and Knife Wall. Take one and the rest are gone for the run.
