How does winning with shallow grave work at instant speed? I must just be missing something obvious.
use the druid to get your library. Cast Shallow Grave to return Body double (copying Lark), which grabs Carrion Thrash and Body Double (copying Lark), with the seond Lark trigger on the stack, sac the first Doby Double to the carrion thrash. 2nd Lark grabs Mogg Fanatic, and Body Double (to copy Lark again). Sac Fanatic to do one damage to the oppoent in reponse to the trigger, and loop infinately. This si the old Flash kill.
Actually, I don't believe that would work. Lark triggers on leaving play. Maybe...
Shallow Grave -> Sharuum -> Sharuum (infi loop of sharuums with a Bridge from Below in your grave) -> Possessed Portal
Shallow Grave -> Karmic Guide -> Kiki-Jiki -> Kiki-Jiki -> Guide -> Sharuum (infi loop of sharuums with a Bridge from Below in your grave) -> Thousand Year Elixir -> untap Kiki -> Guide -> Hua Tuo, Honored Physician -> put anything on top so you don't die -> ???
Shallow Grave -> Infi loop of Bladewing, the Risen with Bridge in grave -> a dragon with devour and haste via dragon breath. Dead effectively at sorcery speed.
Necromancy -> Worldgorger -> Shivan Hellkite/Oona?
