Satoru Umezawa + Great Whale + Sakashima's Student

Satoru Umezawa

Great Whale

Sakashima's Student

How it works

1. Declare Sakashima's Student as an attacker.
2. When it isn't blocked, activate up to seven lands you control by tapping them, adding at least 3.
3. Activate Great Whale's ninjutsu ability by paying 2 and returning Sakashima's Student 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 Sakashima's Student's ninjutsu ability by paying 1 and returning Great Whale from the battlefield to your hand, putting Sakashima's Student onto the battlefield from your hand tapped and attacking as a copy of any nonlegendary creature you control.
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.

This loop is a masterclass in recursive espionage, turning Satoru Umezawa's massive hand-granting ninjutsu discount into a self-sustaining engine. By cycling Great Whale and Sakashima's Student back and forth between your hand and the battlefield, each entry triggers the Whale's massive land-untapping ability to completely refund the mana spent while netting extra profit. Satoru Umezawa even helps you dig through your deck along the way, ensuring you never run out of options while generating infinite mana and endless entry triggers.
