We formulate and prove a combinatorial property assuming $AD + V = L(\mathbb{R})$. As a consequence, we show that every regular $\kappa$ which is either a Suslin cardinal or the successor of a Suslin cardinal is $\delta^2_1$-supercompact. In particular, all the projective ordinals $\delta^1_n$ are $\delta^2_1$-supercompact.
