Scarab God Combo/Stax Hybrid (EDH / Commander)

1) Buried Alive to put Necrotic Ooze, Phyrexian Devourer and Walking Ballista in the yard. Recur Nooze with a spell or SG's ability. Win the game upon resolution by milling your deck to power up Nooze with +1/+1 counters from Devourer's activated ability and then pinging your opponents to death with them via Ballista's activated ability.

2) Mill your library and draw with Laboratory Maniac in play. This can be done 2 ways, one with SG and one without.

2a) Entomb your Mirror-Mad Phantasm. On the end step before your turn, use SG's ability to exile MMP from the yard and put a token of him on the battlefield. Activate the token MMP's ability. Since it is only a token, it will not shuffle back into your deck and as a result you will not find one and your entire library will be milled into the graveyard (this idea came from reddit user u/kelptic183 on the r/cedh sub). During your upkeep after untapping, use SG's ability again to make a Lab Man token, then draw for turn and win.

2b) Have out Mesmeric Orb and either Aphetto Alchemist or Basalt Monolith. Tap and untap infinitely to completely mill your library. This will put Narcomoeba into play. If you need more creatures you can Unearth Fatestitcher for U, and then you can untap a black source of mana with him to cast Gravecrawler from the yard since Fatestitcher is a zombie. Playing a land to get back Bloodghast is also an option. Sac 3 to flashback Dread Return for Lab Man. You will need a draw spell to win this way, so if there are none in hand you can flashback Deep Analysis for 1U and 3 life.

3) If graveyard hate or other interaction is cutting off your main lines, get Illusionist's Bracers out and equipped to Aphetto Alchemist. You can then generate infinite mana with any mana rock (other than Dimir Signet) and use it for a game winning Walking Ballista.
