Dark Polarity

Change the text of enchanted enchantment by replacing all instances of the word "has" with "losses" and all original instances of the symbol
"+" with "-" and of the symbol "-" with "+".
(For example, you may change "enchanted creature gets +1/+1 and has flying" to "enchanted creatures gets -1/-1 and losses flying")
There are those on Theros that practice a perverse art
of channeling the darkness between the constellations.
