Thousand-Faced Shadow + Palinchron + Nezumi Prowler

Thousand-Faced Shadow

Palinchron

Nezumi Prowler

How it works

1. Declare Palinchron and Nezumi Prowler as attackers.
2. When they aren't blocked, activate up to seven lands you control by tapping them, adding at least 3.
3. Activate Thousand-Faced Shadow's ninjutsu ability by paying 2 and returning Nezumi Prowler from the battlefield to your hand, putting Thousand-Faced Shadow onto the battlefield from your hand tapped and attacking.
4. When Thousand-Faced Shadow enters the battlefield, it triggers, creating a token copy of Palinchron that is tapped and attacking.
5. When the Palinchron token enters the battlefield, it triggers, untapping up to seven lands.
6. Activate Nezumi Prowler's ninjutsu ability by paying 1 and returning Thousand-Faced Shadow from the battlefield to your hand, putting Nezumi Prowler onto the battlefield from your hand tapped and attacking.
7. Repeat from step 2.
8. Deal combat damage using the Palinchron tokens, dealing infinite combat damage to the defending opponent.
9. If you control up to seven lands that can tap to produce at least 4, this combo nets infinite mana.
