Satoru Umezawa
Great Whale
Moonblade Shinobi

Requires
Satoru Umezawa must be on the battlefield. Great Whale must be in hand. Moonblade Shinobi must be on the battlefield. Moonblade Shinobi does not have summoning sickness and cannot be blocked by an opponent. You control up to seven lands that can tap to produce at least 4.
Steps
  1. Declare Moonblade Shinobi as an attacker.
  2. When it isn't blocked, activate up to seven lands you control by tapping them, adding at least 4.
  3. Activate Great Whale's ninjutsu ability by paying 2 and returning Moonblade Shinobi from the battlefield to your hand, putting Great Whale onto the battlefield from your hand tapped and attacking.
  4. When Great Whale enters the battlefield, it triggers, untapping up to seven lands.
  5. Activate Moonblade Shinobi's ninjutsu ability by paying 2 and returning Great Whale from the battlefield to your hand, putting Moonblade Shinobi onto the battlefield from your hand tapped and attacking.
  6. Repeat from step 2.
  7. If you control up to seven lands that can tap to produce at least 5, this combo nets infinite mana.
