We derive the first ever on-shell recursion relations applicable to effective field theories.
Based solely on factorization and the soft behavior of amplitudes, these recursion relations
employ a new rescaling momentum shift to construct all tree-level scattering amplitudes in
the nonlinear sigma model, Dirac-Born-Infeld theory, and the Galileon. Our results prove that
all theories with enhanced soft behavior are on-shell constructible.
