Satoru Umezawa + Palinchron + Skullsnatcher

Satoru Umezawa

Palinchron

Skullsnatcher

How it works

1. Declare Skullsnatcher 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 Skullsnatcher 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 Skullsnatcher's ninjutsu ability by paying and returning Palinchron from the battlefield to your hand, putting Skullsnatcher 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 clever loop relies on Satoru Umezawa to grant every creature card in your hand ninjutsu, turning your hand into a revolving door of sneaky threats. By swapping Palinchron and Skullsnatcher back and forth through combat, you constantly trigger Palinchron's entry ability to untap your lands and fund the next swap. As long as those lands produce enough mana, you can repeat this dance indefinitely to generate infinite mana and boundless enter-the-battlefield triggers.
