Jaheira, Friend of the Forest + Spawning Pit + Urabrask the Hidden + Exalted Sunborn

Jaheira, Friend of the Forest

Spawning Pit

Urabrask the Hidden

Exalted Sunborn

How it works

1. Activate Spawning Pit's second ability by paying 1 and removing two charge counters from it, creating two creature tokens
2. Activate the tokens by tapping them, adding .
3. Activate Spawning Pit's first ability twice by sacrificing the tokens, putting two charge counters on Spawning Pit.
4. Repeat.

This clever loop is powered by Jaheira, Friend of the Forest, which grants your tokens the ability to tap for green mana to help sustain the sequence. Spawning Pit acts as both the sacrifice outlet and the token engine, consuming its own charge counters to generate creatures that Jaheira immediately turns into a mana source. To amplify this, Exalted Sunborn doubles every token created to ensure you net a surplus of bodies and mana with each iteration. Meanwhile, Urabrask the Hidden ensures your newly spawned artifacts hit the battlefield ready to tap for mana immediately thanks to its haste-granting static ability, keeping the loop going infinitely.
