Fast, mono blue, aggro deck based on the Untap ability in the Urza block. Use High Tide early on or Gauntlet of Power later on to set up your combo. With islands doubling, each untapping spell or creature results in a growing mana pool. Able to play your Leviathan with three lands, or any huge creature. Palinchron sets up an infinite mana combo which you can use to draw or mill your opponent. Tidespout Tyrant keeps your combos coming if targeting your own untapping creatures or a bit of control when targeting your opponents.
