How it works

3. Activate Earthcraft by tapping an untapped creature, untapping the enchanted land.
4. Activate Marath by paying 1 and removing a +1/+1 counter from it, creating a 1/1 Elemental token.
5. Repeat until Marath has no more +1/+1 counters.
6. Marath dies due to having 0 toughness and goes to the command zone.
7. Cast Marath by paying plus commander tax, leaving zero mana unspent.
