Fairexian

{p/b}{p/b}: Target opponent loses 1 life.
{p/b}{p/b}{p/b}: Target opponent discards a card.
{p/b}{p/b}{p/b}{p/b}: Target opponent sacrifices a creature.
At the beginning of your upkeep, you may pay {x} where X is the total amount of life you paid while activating Fairexian's abilities last turn. If you don't, you lose the game because phyrexian mana is imbalanced and shouldn't be used.
