  4. When Great Whale enters the battlefield, it triggers, untapping up to seven lands.
  5. Activate Mukotai Ambusher's ninjutsu ability by paying 1 and returning Great Whale from the battlefield to your hand, putting Mukotai Ambusher 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 4, this combo nets infinite mana.
