Laddersmith\'s Cursed Route

Enchant Player On enchanted players upkeep, venture into The Gutter, then blight 1 or gain 1 poison counter. When enchanted player completes The Gutter, exile this enchantment and transform it, you may play it without paying its mana cost for as long as it is exiled. If this enchantment leaves the battlefield before the enchanted player completes The Gutter, that player leaves the dungeon.
