AB We present the first systematic feasibility study of accessing generalized parton distributions of the pionat an electron-ion collider through deeply virtual Compton scattering. Relying on state-of-the-art modelsfor pion GPDs, we show that quarks and gluons interfere destructively, modulating the expected event rateand maximizing it when parton content is generated via radiation from valence dressed quarks. Moreover,gluons are found to induce a sign inversion for the beam-spin asymmetry in every model studied, being aclear signal for pinning down the regime of gluon superiority
