How it works
Activate up to seven lands by tapping them, adding at least 4.
Cast Saheeli's Artistry by paying 4, creating a token copy of Palinchron that is an artifact.
When the Palinchron token enters, it triggers, untapping up to seven lands.
Cast Returned Pastcaller by paying its mana cost.
When Returned Pastcaller enters, it triggers, returning Saheeli's Artistry from your graveyard to your hand.
Activate up to seven lands by tapping them, adding at least 4.
Cast Saheeli's Artistry by paying 4, creating a token copy of Returned Pastcaller and the Palinchron token.
When the Returned Pastcaller and Palinchron tokens enter, they trigger.
Resolve the Returned Pastcaller token's trigger, returning Saheeli's Artistry from your graveyard to your hand.
Resolve the Palinchron token's trigger, untapping up to seven lands.
Repeat from step 6.
This ingenious loop hinges on cleverly multiplying your threats using Saheeli's Artistry to copy Palinchron, which completely refunds its own casting cost by untapping your lands upon entering the battlefield. Once you add Returned Pastcaller to the mix, its entry trigger lets you pull Saheeli's Artistry right back out of your graveyard to hand. From there, each iteration of the spell allows you to snowball by cloning both the dragon and the bird simultaneously, generating an unstoppable cascade of enter-the-battlefield triggers, infinite mana, and an army of artifact creature tokens.
