I've noticed some players waiting until saturday/sunday night to play their games because its "easier" to get a higher amount of wins on their weekend ranked games.
my belief in playing on sunday is that most players play their first 25 games on friday so by sunday players aren't trying as hard to win/ using their main deck.
do you believe that player difficulty on the weekend changes depending on which day you play? why or why not and what day you play your games?
