Satoru Umezawa + Great Whale + Kappa Tech-Wrecker

Satoru Umezawa

Great Whale

Kappa Tech-Wrecker

How it works

1. Declare Kappa Tech-Wrecker as an attacker.
2. When it isn't blocked, activate up to seven lands you control by tapping them, adding at least 3.
3. Activate Great Whale's ninjutsu ability by paying 2 and returning Kappa Tech-Wrecker from the battlefield to your hand, putting Great Whale onto the battlefield from your hand tapped and attacking.
4. When Great Whale enters the battlefield, it triggers, untapping up to seven lands.
5. Activate Kappa Tech-Wrecker's ninjutsu ability by paying 1 and returning Great Whale from the battlefield to your hand, putting Kappa Tech-Wrecker onto the battlefield from your hand tapped and attacking.
6. Repeat from step 2.
7. If you control up to seven lands that can tap to produce at least 4, this combo nets infinite mana.

This elegant loop hinges on Satoru Umezawa’s static ability, which grants every creature card in your hand ninjutsu and turns your attackers into a revolving door of mana generation. By sneaking Great Whale into play via ninjutsu, its enter-the-battlefield trigger untaps your lands to easily refund the casting cost and net a profit. You then use Kappa Tech-Wrecker’s cheap ninjutsu ability to bounce the Whale back to your hand while sending the Tech-Wrecker back into the fray, ready to swap places all over again.
