Hexproof, Indestructible.
At the beginning of each opponent's draw step,
that player rolls a d20. If the result is 10 or lower,
that player can't draw cards for the rest of that
turn.
At the beginning of your upkeep, roll a d6, then, create a number of 1/1 black Skeleton creature
tokens equal to the result.
