At the beginning of your upkeep, reveal the top card of your library and put that card into your hand. You lose life equal to its mana value.
"Ours is a path of the outcast, of pain given and pain received. But for the strong, it is a path that leads to power untethered from fae riddles."

The mana value of the revealed card is determined solely by the mana symbols printed in its upper right corner. The mana value is the total amount of mana in that cost, regardless of color. For example, a card with mana cost {3}{U}{U} has mana value 5.

If the revealed card has no mana symbols in its upper right corner (because it's a land card, for example), its mana value is 0.
