Thousand-Faced Shadow + Temur Sabertooth + Great Whale

Thousand-Faced Shadow

Temur Sabertooth

Great Whale

How it works

1. Declare Great Whale and any other creature as attackers.
2. When they are unblocked, activate up to seven lands you control by tapping them, adding at least 4.
3. Activate Thousand-Faced Shadow's ninjutsu ability by paying 2 and returning the other attacking creature to your hand, putting Thousand-Faced Shadow from your hand onto the battlefield tapped and attacking.
4. Thousand-Faced Shadow enters the battlefield, creating a token copy of Great Whale.
5. The token Great Whale enters the battlefield, untapping up to seven lands you control.
6. Activate Temur Sabertooth by paying 1, returning Thousand-Faced Shadow from the battlefield to your hand.
7. Repeat from step 2.
