Sunken Palace
Sunken Palace is an Extended Art blue land with a cave lineage that fits neatly into a slow, control heavy commander shell. The art evokes a submerged throne room, submerged in blue mist and distant echoes, and the card enters the battlefield tapped, which helps you tempo your mana base in multi turn games. On straight draws it provides a reliable source of blue mana once tapped, making it a steady anchor for any ramp or counterspell suite that relies on a late game mana base.
The map to its power lies in a built in graveyard worthy ability. By paying a small mana cost you exile seven cards from your graveyard to produce an additional mana and you gain a copy trigger on the spell or ability you spend that mana to cast or activate. The copy can be redirected to new targets, creating value on spells or activated abilities you would already use, though mana abilities themselves cannot be copied. This dual function rewards deckbuilding that streams graveyard resources into more consistent spell equality and targeted copying while keeping the base mana fix simple and predictable.
