    Happened again today after I edited my monogreen deck. I will keep posting samples in this thread until someone fixes it. It is not possible that it is just a coincidence that the cards I add to the deck show up repeated in the first hand I draw.

    Hi,

    The reason I'm reporting this is because I've seen this happening enough times.

    Whenever I modify or create a new deck, including new cards. Those new cards often show up on my first hand (without Mulligan).

    As you can see here in the screenshot there are multiple pairs of repeated cards that came on my first hand.

    This happened to me certainly multiple times.

    I'm a developer and I suspect that the shuffler algorithm is based on a random library that is probably problematic (ie. if rand() is called multiple times in a short period of time it might return almost the same index entry as almost all random libraries are time-based).

    From a statistics perspective the chance to have such replicable problem is very very low.

    Please double check your code and please improve it.
