Sunken City⁣ - Fourth Edition⁣ (Common)

Sunken City is an enchantment from Fourth Edition that boosts all blue creatures by +1/+1 but requires constant upkeep due to its sacrifice clause unless you pay {U}{U} each turn. This card can significantly enhance your board presence in a blue-heavy deck, making it ideal for aggressive strategies that rely on blue creatures. However, the mana commitment can be a limitation in decks that need to spread their resources thinly across various spells and abilities.
