In this paper, we evaluate a new refined de Sitter (dS) conjecture perspective. This conjecture provides interesting conditions in studying various inflationary models. Therefore, we challenge refined dS conjecture with a general method for analyzing the potentials with the inflectional point near the top (V 00 = 0). We find the compatible spaces for our inflationary model that lives out of swampland according to the latest observational data such as Planck 2018.
