Abstract: The number counts of galaxy clusters are a powerful and 
independent cosmological probe. We review how several challenges in this 
experiment can be overcome by a combination of multi-wavelength data and 
hydrodynamical simulations. Specifically we will discuss how to 
empirically constrain the incompleteness and contamination fraction of 
cluster samples. We will also present an innovative method to quantify 
the accuracy of weak gravitational lensing inferred masses, as well as 
recent applications of this method. In the end, we will look ahead, to 
the opportunities and challenges present by future and starting 
cosmological surveys like eROSITA, Euclid and CMB stage 4.
