  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 number
of flavors. For certain choices of the mass parameters these vacua are not
lifted 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 effective
theory has a simple Lagrangian description involving a free chiral multiplet in
the adjoint representation of the flavor symmetry group, a system somewhat
reminiscent 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-coupled
non-local theories of quarks and monopoles.
