Massive galaxy clusters have been recognized as a powerful tool to probe the evolution of dark energy. Using cluster-galaxy weak lensing, we develop a method for overcoming the difficulty in the standard cluster counting method and constraining cosmological parameters. Clusters are rank-ordered using a mass-observable relation and the top portion of the rank-ordered clusters are further stacked for weak lensing measurement. We first demonstrate the insensitivity of the stacked clusters to the scatter in the mass-observable relation and examine the dependence of the weak lensing signal on cosmological parameters. We then apply our method to the upcoming Dark Energy Survey (DES), forecasting its ability to measure cosmological parameters.
