Gaunt Field Spectre

Hexproof, Lifelink, and Menace
Whenever Gaunt Field Spectre deals damage to a
player, that player discards a card. Until their
next end step, spells cost them {1} more to cast.
It stalks the woods and when the fields are high.
Dread and fear it brings night. Reaping crop and
thought and life. Never go out alone at night."
