Magic the Gathering Core Set 2020

Magic 2020 Core set is here today!
Praise be to the wizards and the highest! The set is made up of 280 cards (112 Commons, 80 Uncommons, 53 Rares, 15 Mythic Rares, 20 Basic Lands), major rules changes for this year are the much-publicized new London mulligan. Draw seven cards every time you mulligan. When you are satisfied, you put cards back on the bottom of your library for each time you have mulliganed. In conjunction with this new friendlier and less punishing mulligan rule are the return of Leylines, cards that give a greater advantage for being in your opening hand.
After the huge success of War of Spark, will Wizards maintain the momentum for a new year of play? Only time will tell if we've entered a new golden age of Magic or if this is just a passing glory like the Onslaught Block.
