Tempt the Unknowable

Enchant creature you control

Enchanted creature gains your choice of three keyword counters. (These can be deathtouch, lifelink, hexproof, etc.)
At the beginning of your upkeep, remove a keyword counter from enchanted creature unless you pay life equal to the number of keyword counters on enchanted creature. If you cannot remove a keyword counter, sacrifice enchanted creature and this enchantment.
