Thousand-Faced Shadow + Palinchron + Covert Technician

Thousand-Faced Shadow

Palinchron

Covert Technician

How it works

1. Declare Palinchron and Covert Technician 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 Covert Technician 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 Covert Technician's ninjutsu ability by paying 1 and returning Thousand-Faced Shadow from the battlefield to your hand, putting Covert Technician 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.

This ingenious loop relies on a clever ninjutsu dance between Thousand-Faced Shadow and Covert Technician to repeatedly redeploy a single copy into an escalating army. Every time Thousand-Faced Shadow enters the battlefield attacking, its triggered ability duplicates the original Palinchron, whose own entry triggers untap your lands to immediately fund the next iteration. Covert Technician then steps in to bounce the Shadow back to safety while resetting the board for another strike, allowing the accumulating Palinchron tokens to overwhelm your opponent with infinite combat damage.
