Thousand-Faced Shadow + Great Whale + Dokuchi Silencer

Thousand-Faced Shadow

Great Whale

Dokuchi Silencer

How it works

1. Declare Great Whale and Dokuchi Silencer 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 Dokuchi Silencer 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 Great Whale that is tapped and attacking.
5. When the Great Whale token enters the battlefield, it triggers, untapping up to seven lands.
6. Activate Dokuchi Silencer's ninjutsu ability by paying 1 and returning Thousand-Faced Shadow from the battlefield to your hand, putting Dokuchi Silencer onto the battlefield from your hand tapped and attacking.
7. Repeat from step 2.
8. Deal combat damage using the Great Whale 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 elegant loop turns the sneaky nature of ninjutsu into a self-sustaining engine by ping-ponging attackers between your hand and the battlefield. Once Great Whale and Dokuchi Silencer slip past your opponent's defenses, you use Thousand-Faced Shadow's ninjutsu ability to bounce the Silencer and bring in a clone-maker that immediately drops a token copy of Great Whale. That newly minted whale untaps your lands to pay for the next shift, allowing Dokuchi Silencer to bounce Thousand-Faced Shadow right back to your hand and restart the cycle. By endlessly swapping these ninjas in and out of play, you generate an army of whale tokens, infinite mana from your untapping lands, and a relentless wave of infinite combat damage.
