Psychic Allergy

Enchantment, 3UU (5)
As Psychic Allergy enters the battlefield, choose a color.

At the beginning of each opponent's upkeep, Psychic Allergy deals X damage to that player, where X is the number of nontoken permanents of the chosen color he or she controls.

At the beginning of your upkeep, destroy Psychic Allergy unless you sacrifice two Islands.¹
