Radagast, Wizard of Wilds + Temur Sabertooth + Phyrexian Altar + Mycosynth Golem + Parallel Lives

Radagast, Wizard of Wilds

Temur Sabertooth

Phyrexian Altar

Mycosynth Golem

Parallel Lives

How it works

1. Cast Mycosynth Golem by paying 0.
2. Radagast triggers, creating two 3/3 Beast creature tokens.
3. Activate Phyrexian Altar twice by sacrificing the Beasts, adding 1.
4. Activate Temur Sabertooth by paying 1, returning Mycosynth Golem from the battlefield to your hand.
5. Repeat.

This loop relies on making Mycosynth Golem completely free to recast, turning it into a repeatable engine that continuously triggers Radagast, Wizard of Wilds to flood the board with tokens. Because Parallel Lives doubles every token created, sacrificing just a few creatures to Phyrexian Altar easily generates more than enough mana to feed Temur Sabertooth's bounce ability. You can simply return the Golem to your hand, replay it for zero mana thanks to its own affinity, and repeat the entire sequence to flood the board and churn through your spells.
