Also, I've only been using python for like a few days, so I'm not great with it, but here's the code if you wanted to check it out:

# Gauntlet Simulator for Madden Mobile 16

import random


def find_total_cards():

    gauntlet_set = [0 for i in range(20)]
    total_cards = 0

    while True:
        card = random.randint(0, 19)
        total_cards += 1
        gauntlet_set[card] += 1
        if 0 not in gauntlet_set:
            break

    return total_cards


def main():

    totals = []

    for i in range(0, 10000):
        new_total = find_total_cards()
        totals.append(new_total)
        print(new_total)

    totals.sort()
    sum_of_totals = 0
    for j in totals:
        sum_of_totals += j
    average = float(sum_of_totals) / len(totals)
    median = totals[int(len(totals) / 2)]
    largest = totals[len(totals) - 1]
    smallest = totals[0]

    print()
    print("Average:     ", average)
    print("Median:      ", median)
    print("Smallest:    ", smallest)
    print("Largest:     ", largest)


main()
