We implement new techniques involving Artin fans to study the realizabilityof tropical stable maps in superabundant combinatorial types. Our approach isto understand the skeleton of a fundamental object in logarithmicGromov--Witten theory -- the stack of prestable maps to the Artin fan. This isused to examine the structure of the locus of realizable tropical curves andderive 3 principal consequences. First, we prove a realizability theorem forlimits of families of tropical stable maps. Second, we extend the sufficiencyof Speyer's well-spacedness condition to the case of curves with goodreduction. Finally, we demonstrate the existence of liftable genus 1superabundant tropical curves that violate the well-spacedness condition.
