Satoru Umezawa + Silver-Fur Master + Palinchron

Satoru Umezawa

Silver-Fur Master

Palinchron

How it works

1. Declare another nontoken creature as an attacker.
2. When the creature isn't blocked by an opponent, activate up to seven lands you control by tapping them, adding at least 3.
3. Activate Palinchron's ninjitsu ability by paying 1 and returning the unblocked creature to your hand, putting Palinchron onto the battlefield tapped and attacking.
4. Palinchron enters the battlefield, untapping the seven lands.
5. Activate any creature card in your hand's ninjitsu ability by paying 1 and returning Palinchron to your hand, putting the creature onto the battlefield tapped and attacking.
6. Activate up to seven lands you control by tapping them, adding at least 3.
7. Repeat from step 3.

This clever engine transforms Satoru Umezawa into a master of economic subversion by blanketing your entire hand in a discounted ninjutsu cost, thanks to Silver-Fur Master's passive cost reduction. Once an initial attacker goes unblocked, you use Palinchron's self-bounce ability to swap back and forth between the Leviathan and any other creature in your hand. Every time Palinchron hits the battlefield, its enter-the-battlefield trigger untaps your lands to completely refund the mana spent, generating an infinite loop of leaves-the-battlefield and enters-the-battlefield triggers along with boundless mana.
