Saheeli's Artistry + Mnemonic Wall + Palinchron

Saheeli's Artistry

Mnemonic Wall

Palinchron

How it works

1. Activate up to seven lands by tapping them, adding at least 4.
2. Cast Saheeli's Artistry by paying 4, creating a token copy of Palinchron that is an artifact.
3. When the Palinchron token enters, it triggers, untapping up to seven lands.
4. Cast Mnemonic Wall by paying its mana cost.
5. When Mnemonic Wall enters, it triggers, returning Saheeli's Artistry from your graveyard to your hand.
6. Activate up to seven lands by tapping them, adding at least 4.
7. Cast Saheeli's Artistry by paying 4, creating a token copy of Mnemonic Wall and the Palinchron token.
8. When the Mnemonic Wall and Palinchron tokens enter, they trigger.
9. Resolve the Mnemonic Wall token's trigger, returning Saheeli's Artistry from your graveyard to your hand.
10. Resolve the Palinchron token's trigger, untapping up to seven lands.
11. Repeat from step 6.

This clever loop revolves around multiplying your enters-the-battlefield triggers by turning Saheeli's Artistry into a multi-purpose engine of replication. By targeting both Palinchron and Mnemonic Wall, a single casting of Saheeli's Artistry not only generates infinite mana through Palinchron's land-untapping ability, but also continuously buys itself back out of the graveyard using Mnemonic Wall. The resulting cascade of copies floods the board with infinite artifacts and creatures while recycling your spells indefinitely.
