We call such a graph \"$H$-deletion-saturated\". This version of the well-studied notion of \"$H$-induced-saturated\" graphs -- where both adding and deleting any edge creates an induced copy of $H$ -- appears more tractable. For example, while it remains wide open whether $H$-induced-saturated graphs exist for every even cycle $H$, we proved recently that deletion-saturated graphs exist for all even cycles.
