Satoru Umezawa + Yuriko, the Tiger's Shadow + Palinchron

Satoru Umezawa

Yuriko, the Tiger's Shadow

Palinchron

How it works

1. Declare Yuriko as an attacker.
2. When it isn't blocked, activate up to seven lands you control by tapping them, adding at least 2.
3. Activate Palinchron's ninjutsu ability by paying 2 and returning Yuriko from the battlefield to your hand, putting Palinchron onto the battlefield from your hand tapped and attacking.
4. When Palinchron enters the battlefield, it triggers, untapping up to seven lands.
5. Activate Yuriko's ninjutsu ability by paying and returning Palinchron from the battlefield to your hand, putting Yuriko 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 3, this combo nets infinite mana.

This elegant looping engine leverages Satoru Umezawa to grant every creature in your hand ninjutsu, turning your attackers into a revolving door of sneaky ninjas. By bouncing and replaying Palinchron over and over, its entry trigger untaps your lands to continuously refund your mana while generating infinite enters-the-battlefield and leaves-the-battlefield triggers. Finally, commander ninjutsu lets you swap Palinchron right back out for Yuriko, the Tiger's Shadow, safely cycling your commander into the fray to press your advantage.
