Riley, Bringer of Chaos

Reach, Menace
At the beginning of your upkeep you may roll
a d20 until you roll a result of 10 or greater, then
you may use that result instead of
another roll this turn
At the beginning of your end step you may cast
spells with mana value X or less, where X is the
amount of coin flips you won this turn
