Squirrel Wrangler + Stonework Packbeast + Mana Echoes + Drownyard Temple

Squirrel Wrangler

Stonework Packbeast

Mana Echoes

Drownyard Temple

How it works

1. Activate Squirrel Wrangler by paying 1 and sacrificing Drownyard Temple, creating two 1/1 Squirrel creature tokens.
2. Both Squirrel tokens enter the battlefield, triggering Mana Echoes twice.
3. Resolve both Mana Echoes triggers, adding CC for each Squirrel on the battlefield.
4. Activate Drownyard Temple by paying 3, returning it from your graveyard to the battlefield tapped.
5. Activate Stonework Packbeast by paying 2, adding .
6. Repeat.

This loop transforms a modest sacrifice into an unstoppable engine by leveraging Mana Echoes to turn each influx of new creatures into a massive bounty of colorless mana, made possible because Stonework Packbeast's flexible typing ensures every single token shares a creature type to maximize the echo. To keep the cycle going, Squirrel Wrangler happily devours Drownyard Temple for fuel, which is then immediately revived straight from the graveyard using its own recursion ability. The result is a self-sustaining web of life and soil that floods the battlefield with infinite squirrels, infinite power, and all the mana you could ever possibly need.
