Thousand-Faced Shadow + Great Whale + Mistblade Shinobi

Thousand-Faced Shadow

Great Whale

Mistblade Shinobi

How it works

1. Declare Great Whale and Mistblade Shinobi 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 Mistblade Shinobi 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 Mistblade Shinobi's ninjutsu ability by paying and returning Thousand-Faced Shadow from the battlefield to your hand, putting Mistblade Shinobi 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 cunning loop relies on an endless exchange of attackers using the ninjutsu mechanic to repeatedly trigger powerful entry effects. By returning Mistblade Shinobi to your hand, you make room for Thousand-Faced Shadow to enter the battlefield and clone Great Whale, whose entry ability untaps your lands to pay for the next cycle. Mistblade Shinobi can then ninjutsu back onto the board by bouncing Thousand-Faced Shadow, setting you up to generate boundless mana, creature tokens, and a lethal army of attacking whales.
