Marath, Will of the Wild + Cryptic Trilobite + Doubling Season

Marath, Will of the Wild

Cryptic Trilobite

Doubling Season

How it works

1. Activate Marath by paying 1 and removing a +1/+1 counter from it, putting two +1/+1 counters on Marath.
2. Activate Marath by paying 1 and removing a +1/+1 counter from it, putting two +1/+1 counters on Cryptic Trilobite.
3. Activate Cryptic Trilobite's first ability by removing a +1/+1 counter from it, adding CC that can only be spent to activate abilities.
4. Repeat.
5. Once Cryptic Trilobite has infinite +1/+1 counters, you may remove them for infinite mana, then repeat step 1 to get infinite +1/+1 counters on Marath, which can then be used for Marath's other modes.

This loop relies on Doubling Season to turn every counter-placement effect into a net gain, allowing Marath, Will of the Wild to grow larger while generating extra resources. By using Marath's ability to pump Cryptic Trilobite, you can feed Cryptic Trilobite's mana-producing ability to fuel the entire sequence. Once Cryptic Trilobite has accumulated infinite +1/+1 counters, you can easily tap into infinite colorless mana restricted to activating abilities, enabling you to close out the game with Marath's damage and token-creation modes.
