  In this work, we present an effective field theory for string inflation with
spontaneously broken supersymmetry without generating any supersymmetric
anti-de Sitter vacua. In that regard, we analyze the nilpotent superfields that
effectively capture the physics of anti-D3 branes, and obtain the underlying
pattern of universal attractors with a single parameter. Accordingly, we reveal
a novel uplifting method by adding the same parameter as a complex contribution
parallel to the decomposition of a superfield. Following that, we obtain an
almost vanishing cosmological constant in a region where the inflationary
attractors unify. Finally, we show that the introduction of nilpotent
superfields drastically extends the string landscape for the de Sitter
(swampland) conjecture, and the (super)universal attractors are in the string
landscape in that respect.
