Death's Oasis + Plargg, Dean of Chaos // Augusta, Dean of Order + Aluren + Carrion Feeder

Death's Oasis

Plargg, Dean of Chaos // Augusta, Dean of Order

Aluren

Carrion Feeder

How it works

1. Cast Augusta from your hand by paying 0 due to Aluren.
2. Activate Carrion Feeder by sacrificing Augusta.
3. When Augusta dies, Death's Oasis triggers, causing you to mill two cards and return Plargg from your graveyard to your hand.
4. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
5. Repeat.

This clever loop turns the back side of Plargg, Dean of Chaos // Augusta, Dean of Order into an endless sacrifice fodder thanks to Aluren, which lets you cast Augusta for free without paying mana costs. Once Augusta is on the battlefield, you feed it directly to Carrion Feeder, whose activated ability pumps it up with infinite +1/+1 counters. Each time Augusta goes to the graveyard, Death's Oasis triggers to mill your library and conveniently pull Plargg back to your hand, setting up the next iteration.
