Leviathan⁣ - Time Spiral⁣ (Time Shifted)

Leviathan is a massive 10/10 creature from the Time Spiral Timeshifted set with trample. It enters the battlefield tapped and requires you to sacrifice two Islands to untap it during your upkeep, as well as to attack, making it a hefty investment in blue mana. This card works well in dedicated control decks that can efficiently manage their resources, but be mindful of its limitations; if you can't maintain those Islands, Leviathan will stay dormant. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
