Doppelgang at X=5 creates five Eternal Witness tokens alongside five copies of each mana-producing permanent; the Witness triggers return Doppelgang to hand, and seventeen of the new mana tokens fund the next cast. The Simic ramp and token shell is the natural home — commanders like Aesi, Tyrant of Gyre Strait or Shorikai, Genesis Engine that already stockpile mana and permanents hit the prerequisite threshold without bending the deck.

Recipe

How it works

Prerequisites

There are four permanents on the battlefield that can collectively tap to produce at least .

Steps

Cast Doppelgang by paying , creating five token copies of Eternal Witness and of the four mana-producing permanents.
When the Eternal Witness tokens enter the battlefield, they trigger, returning Doppelgang and up to four other cards from your graveyard to your hand.
Activate seventeen of the mana-producing permanent tokens by tapping them, adding at least .
Repeat.
Once you have infinite tokens and mana, you may instead target any other permanents using Doppelgang.

Result

Infinite copies of all permanents; Infinite creature tokens; Infinite ETB; Infinite landfall triggers; Infinite magecraft triggers; Infinite mana permanents you control can produce; Infinite storm count; Return all cards from your graveyard to your hand; Infinite casts of instants and sorceries in your hand and graveyard

Variations

Cheaper, tighter, alternate lines

The entry cost is the real obstacle: demands a serious ramp base or cost-reduction effects like Wilderness Reclamation and Kinnan, Bonder Prodigy to hit reliably. Once the loop is running, Doppelgang targets anything, so no separate kill card is needed — the win condition is already on the battlefield, just pick the most threatening permanent in play and copy it until the table concedes.
