Thousand-Faced Shadow + Palinchron + Skullsnatcher

Thousand-Faced Shadow

Palinchron

Skullsnatcher

How it works

1. Declare Palinchron and Skullsnatcher as attackers.
2. When they aren't blocked, activate up to seven lands you control by tapping them, adding at least 2.
3. Activate Thousand-Faced Shadow's ninjutsu ability by paying 2 and returning Skullsnatcher 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 Skullsnatcher's ninjutsu ability by paying and returning Thousand-Faced Shadow from the battlefield to your hand, putting Skullsnatcher 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 3, this combo nets infinite mana.

This cunning loop sets up a perpetual motion machine of ninjutsu and clones, turning your lands and attackers into a cascade of value. By using Thousand-Faced Shadow's entry trigger to perpetually copy Palinchron, you refresh your mana supply every time the token untaps your lands. Meanwhile, Skullsnatcher acts as the cheap enabler that bounces Thousand-Faced Shadow back to your hand for a single black mana, only to immediately trade places and repeat the cycle while building an overwhelming army of flyers.
