  We study 3d $\mathcal{N}=2$ dualities arising from the compactification of 4d
$\mathcal{N}=1$ $Usp(2 n)$ SQCD with two antisymmetric rank-two tensors and
$D_{k+2}$-type superpotential, with odd $k$. The analysis is carried out by
using field theory methods and by checking the various steps on the three
sphere partition function. Most of the results are based on a conjectural
confining duality that we do not prove but that fits consistently with the web
of dualities that we obtain. Along the analysis we recover dualities already
claimed in the literature and we propose new ones. The final picture that
emerges fits with the general scheme worked out for ordinary SQCD and for
adjoint SQCD with $A_k$-type superpotentials.
