Kenrith, the Returned King + Relic of Legends + Agatha of the Vile Cauldron + Saffi Eriksdotter

Kenrith, the Returned King

Relic of Legends

Agatha of the Vile Cauldron

Saffi Eriksdotter

How it works

1. Activate Kenrith's fifth ability by paying due to Agatha, returning Saffi Eriksdotter from your graveyard to the battlefield.
2. Activate Relic of Legends' second ability by tapping Saffi Eriksdotter, adding .
3. Activate Saffi Eriksdotter by sacrificing it.
4. Repeat.

This clever loop hinges on Agatha of the Vile Cauldron, whose passive cost-reduction ability shrinks Kenrith, the Returned King's black revival activation down to a single mana. Relic of Legends provides the necessary mana engine by turning our newly revived legend into a tapped resource, tapping Saffi Eriksdotter to pay for the ability. Meanwhile, Saffi Eriksdotter's own sacrifice effect sets up a self-sustaining loop by constantly returning herself to the battlefield whenever she goes to the graveyard, generating an endless cascade of triggers.
