Radagast, Wizard of Wilds + Adrix and Nev, Twincasters + Temur Sabertooth + Phyrexian Altar + Sojourner's Companion

Radagast, Wizard of Wilds

Adrix and Nev, Twincasters

Temur Sabertooth

Phyrexian Altar

Sojourner's Companion

How it works

1. Cast Sojourner's Companion 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 Sojourner's Companion from the battlefield to your hand.
5. Repeat.

This cunning loop relies on casting Sojourner's Companion for free thanks to its affinity for artifacts, which triggers Radagast, Wizard of Wilds to reward your high-mana-value spell with creature tokens. Because Adrix and Nev, Twincasters doubles every token generated, each cast yields a pair of Beasts that you can immediately feed to Phyrexian Altar to generate the exact mana needed. Finally, Temur Sabertooth uses that recycled mana to bounce Sojourner's Companion right back to your hand, ready to be cast all over again in an endless cycle.
