In every case he is a great player and that he dominates the leaderboard in that way cannot come alone from his cards cause there are other players who have the same cards. I am also curious if it's intention and instinct or artificial intelligence, but I guess in the end it's both.
Another point what make me curious is if it will a player (or more) who will be able to beat him - not in a single fight - this can do many, but in a season - we will see, but I guess in this season he will keep his first place till season end ... in the next season the cards will be mixed again.
