This clever loop relies on Satoru Umezawa to grant every creature card in your hand ninjutsu for {2}{U}{B}, allowing you to bypass normal casting restrictions. By leveraging Palinchron's entry trigger to untap your lands—recovering the mana spent to bounce and replay it—you can alternate returning it to your hand using Dokuchi Silencer's cheaper ninjutsu cost. This perpetual tag-team not only generates infinite mana and entry triggers, but also lets you constantly cycle through your attackers while leaving Satoru Umezawa's triggered ability to dig deeper into your library for answers.
