Shaw, Hellfire King

If a source would deal damage greater than Shaw,
Hellfire King's power to you or Shaw, instead
create a treasure token and put X +1/+1 counters
on Shaw, where X is the difference, then
that source deals that damage.

{t}, {b}: Reveal the top card of your library. You
may put it into your hand. If you do, Shaw deals
damage to you equal to that card's mana value.
