Feared Unicorn

Cumulative Upkeep {1} "(At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.)"
If Feared Unicorn leaves play, target player loses life equal to the number of age counters on it.
"Its' presence was worthy of my most secret nightmares." -Hanna, Weatherlight Navigator
