Final Destiny

Enchant player
At the beginning of enchanted player's upkeep, he or she sacrifices a creature if he or she has 10 life or higher, plus discards a card if he or she has 20 life or higher, plus puts the top five cards of his or her library into his or her graveyard if he or she has 30 life or higher, and loses the game if he or she has 40 life or higher.
Absolute power corrupts absolutely.
