  Kutasov-Schwimmer (KS) dualities involve a rank-$2$ field with a polynomial
superpotential. We derive KS-like dualities via deconfinement, that is assuming
only Seiberg-like dualities, which instead just involve fundamental matter. Our
derivation is split into two main steps. The first step is the construction of
two families of linear quivers with $p\!-\!1$ nodes that confine into a
rank-$2$ chiral field with degree-$(p\!+\!1)$ superpotential. Such chiral field
is an $U(N)$ adjoint in 3d and an $USp(2N)$ antisymmetric in 4d. In the second
step we use these linear quivers to derive, via deconfinement, in a relatively
straightforward fashion, two classes of KS-like dualities: the Kim-Park duality
for $U(N)$ with adjoint in 3d and the Intriligator duality for $USp(2N)$ with
antisymmetric in 4d. We also discuss the close relation of our 3d family of
confining unitary quivers to the 4d $\mathcal{N}\!=\!2$ $D_p[SU(N)]$ SCFTs by
circle compactification and various deformations.
