Satoru Umezawa + Palinchron + Moonblade Shinobi

Satoru Umezawa

Palinchron

Moonblade Shinobi

How it works

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 Palinchron's ninjutsu ability by paying 2 and returning Moonblade Shinobi 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 Moonblade Shinobi's ninjutsu ability by paying 2 and returning Palinchron 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.
