Jarad, Golgari Lich Lord + Cosmogoyf + Phyrexian Devourer

Jarad, Golgari Lich Lord

Cosmogoyf

Phyrexian Devourer

How it works

1. Activate Phyrexian Devourer by exiling the top card of your library.
2. Repeat step 1 until your library is empty or the number of cards you own in exile is equal to or greater than each opponent's life total.
3. Activate Jarad by paying 1 and sacrificing Cosmogoyf, causing each opponent to lose life equal to Cosmogoyf's power.
4. Activate Phyrexian Devourer's second ability by exiling the top card of your library, causing you to put a number of +1/+1 counters on Phyrexian Devourer equal to that card's mana value.
5. Repeat step 1 until Phyrexian Devourer's power is greater than each opponent's life total.
6. Phyrexian Devourer's first ability triggers.
7. Holding priority, activate Jarad by paying 1 and sacrificing Phyrexian Devourer, causing each opponent to lose life equal to Phyrexian Devourer's power.

This explosive combo uses Phyrexian Devourer as a massive engine of self-exile and growth, rapidly eating through your library to balloon its own power or fuel Cosmogoyf's exile-based stat growth. Because Phyrexian Devourer's triggered ability forces you to sacrifice it only when its power hits 7 or greater, you can hold priority with that trigger on the stack and leverage Jarad, Golgari Lich Lord's activated ability to fling the giant creature directly at your opponents' faces. By using Jarad, Golgari Lich Lord to sacrifice whichever heavy-hitting threat you've built up, you convert that staggering power into direct life loss to close out the game in one fell swoop.
