2. Saffi dies, triggering Pitiless Plunderer, creating a Treasure token.
3. Resolve the Saffi ability.
4. Activate Phyrexian Altar by sacrificing Lurrus, adding .
5. When Lurrus dies, Saffi and Pitiless Plunderer trigger.

This ingenious loop uses Saffi Eriksdotter to repeatedly rescue Lurrus of the Dream-Den from the graveyard, utilizing Lurrus's own ability to recast Saffi from the graveyard each time. Meanwhile, Phyrexian Altar provides a convenient sacrifice outlet while filtering the mana needed to keep the cycle going. Pitiless Plunderer ties the whole mechanism together by generating Treasure tokens upon creature deaths, which then supply the exact colors required to recast Saffi repeatedly.
