abstract = {We present the first systematic feasibility study of accessing generalized parton distributions of the pion
at an electron-ion collider through deeply virtual Compton scattering. Relying on state-of-the-art models
for pion GPDs, we show that quarks and gluons interfere destructively, modulating the expected event rate
and 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 a
clear signal for pinning down the regime of gluon superiority},
