Rap God

Indestructible
At the beginning of your end step, look at the
top five cards of your library. Exile one card
face-down, and put the rest on the bottom of
your library in any order.
{t}: Reveal X cards from your hand or from
face-down exile. If you can make all of them
rhyme in a rap, add 2*X mana of any color.
It can only be spent to cast those spells.
Devotion to the hood.
