We revisit the study of singular points in the Coulomb branch of$\mathcal{N}=2$ SQCD in four dimensions with gauge group $SU(N)$ and odd numberof flavors. For certain choices of the mass parameters these vacua are notlifted by a mass term for the chiral multiplet in the adjoint representation.By using recent results about the M5 brane description of $\mathcal{N}=1$theories we study the resulting vacua and argue that the low-energy effectivetheory has a simple Lagrangian description involving a free chiral multiplet inthe adjoint representation of the flavor symmetry group, a system somewhatreminiscent of the standard low-energy pion description of the real-world QCD.This fact is quite remarkable in view of the fact that the underlying$\mathcal{N}=2$ SCFT (the Argyres-Douglas systems) are strongly-couplednon-local theories of quarks and monopoles.
