  We investigate some properties of a black hole in a Horndeski gravity theory
mimicking Einstein-Gauss-Bonnet (EGB) gravity at $D \rightarrow 4$. Borrowing
ideas from quasitopological gravities provide a matter source of dyonic fields,
in which the black hole solution carries two charges, electric and magnetic, in
the context of the EGB gravity. However, due to several limitations of the EGB
gravity in $D \rightarrow 4$, we consider a Horndeski gravity theory which can
mimic EGB gravity in $D \rightarrow 4$. The essential practice used in this
paper is the electromagnetic quasinormal modes process, with the goal of
discovering the spectrum of such an electromagnetic perturbation over the black
hole spacetime. The Wentzel-Kramer-Brillouin (WKB) approximation is used to
achieve the desired results. The study shows that both the charges have similar
impacts on the quasinormal modes.
