Matt, Master Mathematician

When Matt attacks, he gets +X/+Y and you draw
Z cards, where X is the greatest difference between
hand sizes among players or the power of the
creature card with the greatest mana value in
graveyards, whichever is greater, Y is the absolute
value of the difference between tokens and counters
on permanents on the battlefield, and Z is the
expected number of winning players if each player
were to flip a coin, rounded down.
Math, no longer just for blockers.
