at the beginning of your upkeep, exile the top card of your library. you lose life equal to its mana value. you may play that card this turn. praise him — whenever chaos ensues, choose a color. put x +1/+1 counters on target creature you control, where x is your devotion to that color. then sacrifice another creature. (your devotion to a color is the number of mana symbols of that color in the mana costs of permanents you control.)
