# Average Turn Kill Simulator - Muck Rats
# Alters Land and Muck Rats counts. Performs no mulligan actions and assumes 
# the play (no card drawn on first turn). Incorporates psuedo and quasi goldfish 
# behavior. Psuedo-goldfish interacts based on conditional criteria and 
# interaction counts. Quasi-goldfish interacts based on stochastic outcome.
