The Result

"Mills the opponent's entire library (one-sided deck-out)"

Required Cards

Goblin Welder

Welds Phyrexian Devourer onto the battlefield from the graveyard, swapping it for another artifact at instant speed

Phyrexian Devourer

Exiles the library to load up on +1/+1 counters, becoming arbitrarily large

Altar of Dementia

Sacrifice outlet: mills the opponent for the creature's (huge) power

Execution Steps

1

Get Phyrexian Devourer onto the battlefield. Goblin Welder can weld it in from the graveyard, sacrificing a spare artifact, so it never has to be hard-cast.

2

Activate Phyrexian Devourer, exiling cards from the top of your library to pile on +1/+1 counters. Hold priority while its sacrifice trigger (power 7+) is on the stack.

3

In response, sacrifice Phyrexian Devourer to Altar of Dementia, milling the opponent for a number of cards equal to the Devourer's now-enormous power.

4

Mill the opponent's entire library; they lose on their next draw.

Important Rules Notes

Phyrexian Devourer's triggered ability sacrifices it once its power reaches 7 or greater, so you must respond to that trigger (or sacrifice it to the Altar with the trigger on the stack) before it dies on its own, so you keep the accumulated power for the Altar's mill. Goblin Welder is the resilient enabler here: it recurs the Devourer from the graveyard and dodges artifact removal.
