[@Ryougu] I used to run three DeadBridge Chants and full scavenge. If you keep it up with Elixir of Immortality, preferably 4 of them, your opponent will be hard pressed to outlast you, particularly if you keep Treasured find on hand for emergencies. Then again, I also ran a 95 card deck, to protect myself from mill decks.

In the end, though, what you really want for Golgari is Corpsejack menace. Pump up your Corpsejack until he's nigh invincible, then drop Jarad and use his ability to sacrifice your massive Corpsejack. You can kill everyone at the same time, no matter how overwhelmed you are.

Bonus points if your corpsejack has a Vial of Poison and a Fireshrieker


EDIT: If you added Deadbridge chant to your CS, it would likely be a really cool gradual summon, like a slow Zombie Apocalypse, so She wouldn't have to expend so much mana, and still be able to get a creature out every turn.
