Lilith, Hell's Ultimate Fiend

At the beginning of your upkeep, sacrifice a creature and put a soul counter on Lilith. Lilith gets +1/+1 for each of them. For the second, she gains hellbound, for the third, trample, for the forth, flying, for the fifth, indestructible. When Lilith has seven soul counters, you win the game.
If you control Luzifer, Risen from hell, you may have target opponent sacrifice a creature instead
of yourself.
The end has come.
