Twin Rush is a legendary major card out of the New mechanic pool. Driving Rush gains a second charge; each rush is 0.25 s and shoves for 30% of your Main.

You can take it once · it only turns up when your Dash 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 Battering Rush and Long Rush. Take one and the rest are gone for the run.
