Cast Anikthea from your hand or from the command zone by paying 2 plus commander tax, if applicable.
When Anikthea enters the battlefield, it and Life Finds a Way trigger.
Resolve the Anikthea trigger, exiling Oblivion Ring from your graveyard and creating two token copies of it that are 3/3 Zombies.
When the Oblivion Ring tokens enter the battlefield, their first abilities trigger.
Resolve the first Oblivion Ring trigger, exiling Anikthea until the Oblivion Ring token leaves the battlefield.
Resolve the second Oblivion Ring trigger, exiling the first Oblivion Ring token.
When the first Oblivion Ring token is exiled, Anikthea returns to the battlefield from exile.
When Anikthea enters the battlefield, it and Life Finds a Way trigger.
Resolve the Anikthea trigger, choosing not to exile anything.
Resolve the Life Finds a Way trigger, creating two token copies of the Oblivion Ring token.
Repeat from step 4.
This clever loop sets up an infinite engine centered on Anikthea, Hand of Erebos, whose entry trigger copies Oblivion Ring from your graveyard as a 3/3 Zombie token. Thanks to Adrix and Nev, Twincasters doubling your token generation, you actually create two Oblivion Ring tokens that immediately trap Anikthea and each other, initiating a cascading flicker loop. Every time Anikthea bounces back to the battlefield, Life Finds a Way spots her as a nontoken creature with power 4 or greater, triggering its populate ability to flood the board with endless Zombie tokens.
