In large formats like Modern and Extended, there's a tradition of combo decks getting mashed together -- the Daru Spiritualist life combo and Cephalid Breakfast; Dark Depths and Thopter Foundry; various Collected Company and Birthing Pod combinations. Today's deck takes that concept a step further:

This deck is a crazy combination of cards. It starts with Deceiver Exarch and Kiki-Jiki, Mirror Breaker. This, combined with a dense suite of Faithless Lootings and Cathartic Reunions to help you find your combo pieces, gives you the terrifying ability to end games out of nowhere. In addition to that, you have the ability to pitch your combo pieces into the graveyard and use As Foretold to cheat your combo into play with Living End.

On top of that angle, you get to use Goryo's Vengeance and Living End to cheat Griselbrand into play. After drawing seven a couple times, you should have no trouble using Simian Spirit Guide to loot your combo pieces into the graveyard, cast an As Foretold, and end the game from there.

If you're looking for a new unfair thing to do in Modern, this mashup of fan favorite combos seems like an interesting and synergistic approach to killing your opponents quickly.
