This loop transforms Selvala, Heart of the Wilds into a self-contained mana and draw engine by leveraging Temur Sabertooth's ability to bounce creatures to hand and replay them. Because Selvala taps to generate mana equal to the greatest power among creatures you control—boosted passively by Nahiri's Resolve, which also grants haste so she can tap immediately upon re-entering—replaying her continuously yields a net positive surplus of mana. Every iteration of recasting Selvala triggers her own card-draw ability while churning through an endless cycle of creature enter-the-battlefield and leave-the-battlefield events.
