Once a center for knowledge, Sea Gate now serves as a reminder of what was lost.

Oath of the Gatewatch

{T}: Add {C} to your mana pool. ({C} represents colorless mana.)
{2}{C}, {T}: Draw a card. Activate this ability only if you have no cards in hand.

It doesn’t matter how many cards are in your hand as the last ability resolves. For example, if you have no cards in hand and control two Sea Gate Wreckages, you can activate the last ability of each of them. You’ll draw a card as each ability resolves.
