Scammish: Magic the Gathering Arena Mobile App RNG (MtGA)

This may be more broken RNG than it is a scam, although according to other netizen's anecdotes could be scammish favoring P2W. P2W is too difficult for me to analyze. I do not have any suspicions of it but I do not think I could tell. Definitely, there are players with cards that completely trump any of my decks but it is not like those cards are inaccessible to me... and I can see F2P players potentially grinding to have those cards. Those decks are pretty rare to play against, and I suppose I am fine with it once in a while. It is kind of cool to see some rarer cards. 


A mono-color red deck with 25 lands of a 60 card deck
  • 80% of my starting hands have two lands.
    • With more than 33% of my deck being land, I should on average 2-3 two lands on equal ratios
    • On very rare occasions I have one land. Maybe once in a hundred games (~about once a week while playing around 30 games a day)
  • Many of my starting hands that more than two lands come only after multiple losses
  • Several hands where I have all the same non-land cards
    • several games where opponent has all 4 of the same non-land cards within 3-5 rounds
    • For poker fans, the odds of getting a four of a kind 0.02% chance in 5 cards and 0.1% chance in 7 cards. So the odds of getting all four with a 60 card deck vs 52 card deck is lower. 
  • Each day, I may get what seems like two normal games where the opponent and I get a normal distribution of lands
  • Majority of games, the opponent always has the right amount of lands and correct land to play multi-color decks
    • I have faced several multi-color decks that have been able to get play lands each round and has one of each color to play very rare legend cards at exactly five rounds while I almost always struggle to get more than two of a single color.
  • I have faced several games where I go on a drought pulling 10+ cards multiple times
    • With 33% lands, 5 non-land cards in a row would be a 13.5% chance.
  • I have also faced several games where I get 10+ lands within the first 20 cards
    • I get nearly half my lands after 13 pulls which typically starts with 2 lands
    • With 33% lands, 5 land cards in a row would be 0.3% and 7 in a row would be 0.04%
    • I have also played games where I draw 6-8 consecutive lands
  • Opponent always seem to have land. On very, very, very rare case I will see an opponent have any sort of drought. I have several games with only 2-3 lands the entire game. My opponents always have at least 4, and reach 8 lands on a very regular basis and always has spells.
    • Opponent very rarely has land drought. I have maybe seen this 5 times after hundreds of games. Maybe once a day, I'll have
  • Deck contains about 6 cards pertaining to creating creatures or creature spells. On many occasions, I will get all creature spells at the start of the game. 


Occasionally, I play multiple colors
  • There have been many games where I would get 3 lands of one type and 4 cards of the other type. For example, there have been several games I would get 3 plains with 4 green spells or 3 forests with 4 white spells
    • This is also a good number of games when only looking at only starting with 3 land hands which in itself is already rare
  • With nearly half the deck with lands (28 lands in a 60 card deck), majority of the time I only see two lands.
  • Not only is two lands the norm, several times I will not see another land for another 5 or 6 cards.
    • Many of the times I go on a drought, I also face very low odd decks where they run 3-5 colors. And they have always get the lands that they need while I barely get two colors on equal frequency as my opponents.

Matchups
  • I am always able to find opponents at any time of day. With absolutely no evidence, I suspect most of my opponents are not real players (ie bots, employees, not actual random people, etc).

EDIT 2011-11-14

After this post, my land distributions seem to have improved a bit. I will have about 3-4 lands after 20 cards. This at least is playable and have been able to win on rare occasions.

Interview: Can you put this deck of cards in order?

Can you put this deck of cards in order?


I wish I had this question in an interview before I read the article because I am not sure how I would have reacted to this question. I have a slight feeling that I may have just sorted the deck right there because it was something I used to enjoy doing when I was bored at some random place that had a deck of cards way back in the day.

On the other hand, I should have had enough experience to know there is something else that the interviewer is looking for. What order? Why do you want me to do that? Are you crazy? Ok, maybe not the last question but still probably better than just start sorting in silence.

Unfortunately, I read the description and it spoiled what I should not have known. What I like about this question is that this is actually very common type of request from "clients" in any industry. There are three main questions that needs to be asked: time, quality, and cost.

1. How much time do I have to sort the deck?
2. How well do you want the deck sorted?
3. How much are you willing to pay to have the deck sorted?

Most people's questions will probably revolve around quality. How do you want it sorted? So I would figure if you asked questions that answer the other two, you'd be ahead of the competition.

On revisiting this question, I think it would also be good to also demo certain sorts even if it is very simple to explain. For example while asking the interviewer (treated as a client) how they want it sorted, I would suggest some alternatives. "Perhaps you would like it sorted by suits" and separate the cards into 4 piles of the different suits. "Perhaps you prefer it sorted by odds and events" and separate the cards into 2 piles of evens and odds. When reaching a face card and ask "how do you want to treat face cards?" Maybe at the end show a card trick.
