Marath must be your commander.
plus enough mana to pay for commander tax, if applicable available

   Steps

How does this combo work?
1
Cast Marath from the command zone by paying and commander tax, if applicable, causing it to enter the battlefield with a number of +1/+1 counters on it equal to the amount of mana spent to cast it.
2
When Marath enters the battlefield, Mana Echoes triggers, adding for each Elemental and Beast on the battlefield.
3
Activate Marath by paying 1 and removing a +1/+1 counter from it, creating a 1/1 Elemental creature token.
4
When the Elemental enters the battlefield, Mana Echoes triggers, adding for each Elemental on the battlefield.
5
Repeat from step 3 until Marath has one +1/+1 counter on it.
6
Activate Marath by paying 1 and removing a +1/+1 counter from it.
7
Marath dies as a state-based action due to having zero toughness.

Choose to return Marath to the command zone from your graveyard.
