Thousand-Faced Shadow + Palinchron + Moon-Circuit Hacker

Thousand-Faced Shadow

Palinchron

Moon-Circuit Hacker

How it works

1. Declare Palinchron and Moon-Circuit Hacker 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 Moon-Circuit Hacker 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 Moon-Circuit Hacker's ninjutsu ability by paying and returning Thousand-Faced Shadow from the battlefield to your hand, putting Moon-Circuit Hacker 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 loop turns the battlefield into a rotating door of ninjas and illusions, all powered by Palinchron's generous land-untapping entrance. By using Moon-Circuit Hacker's cheap ninjutsu cost to swap out Thousand-Faced Shadow—which continuously clones Palinchron on its way in—you generate more than enough mana from your lands to pay for every bounce and cast. The original Palinchron stays safe in the mix while an endless army of token copies swings in for infinite combat damage, leaving your opponent completely overwhelmed.
