Tropical geometry is sensitive to embeddings of algebraic varieties inside toric varieties. The purpose of this article is to advertise tropical modifications as a tool to locally repair bad embeddings of plane curves, allowing the re-embedded tropical curve to better reflect the geometry of the input curve. Our approach is based on the close connection between analytic curves (in the sense of Berkovich) and tropical curves. We investigate the effect of these tropical modifications on the tropicalization map defined on the analytification of the given curve.Our study is motivated by the case of plane elliptic cubics, where good embeddings are characterized in terms of thej-invariant. Given a plane elliptic cubic whose tropicalization contains a cycle, we present an effective algorithm, based on non-Archimedean methods, to linearly re-embed the curve in dimension 4 so that its tropicalization reflects thej-invariant. We give an alternative elementary proof of this result by interpreting the initial terms of theA-discriminant of the defining equation as a local discriminant in the Newton subdivision.
