MTG Salvation

Hello!

I'm currently working on a Lyzolda deck and since she likes gutting her minions, I want lots of graveyard effects along the lines of...

Vicious Shadows
or
Grave Pact

Clearly the colors are Red and Black.

Impress me with your knowledge!

Butcher of Malakar - Grave pact on a creature
Nether Traitor - Similar to Bloodghast except its nearly unblockable and always has haste
Nim Deathmantle - creature recursion for 4
Su Chi - Gain 4 when it dies

Black Market will give you more mana.
Deathbringer Thoctor would definitely be an include.
Goblin Sharpshooter likes guys dying.
Massacre Wurm likes opponent's guys dying.
Pawn of Ulamog will give you more mana and guys for Skullclamp, etc.
Blade of the Bloodchief can make a guy bigger.
Deathrender can keep feeding you guys from your hand onto the battlefield.
Lightning Coils can eventually charge up and give you more guys to sac to Lyzolda.
Mimic Vat is great if you're running enough utility guys.
Skullclamp loves guys dying!
Thornbite Staff is another Goblin Sharpshooter effect.

Some of those are definitely good enough to include.

Abyssal Gatekeeper...too pro to be used without Grave Pact.

On the "profit" end:
Skullclamp
Butcher of Malakir

On the "minion" end:
Bloodghast
Nether Traitor
Reassembling Skeleton
Siege-Gang Commander
Goblin Assault
Bitterblossom
Marsh Flitter

Greater Gargadon is useful for a sac outlet plus big vanilla beater.
Ashnod's Altar for saccing plus ramp and combos with any creature that brings two more with it (like SG Commander/Flitter) and Nim Deathmantle for infinite mana and infinite tokens = also known as "winning" with Lyzolda.

Not trying to be a smartass, but you will have 142 options that are not in green, blue, or white via:

When I learned how to gatherer searches more efficiently, many doors opened up.

Just figured I'd drop a quick plug for my Lyzolda deck, link's down in my signature.

Most of the better cards have been listed already, but one of the main things to remember about is that there's so much synergy between the two colors. It seems like with my deck there are no two cards that don't interact with each other, and with Lyzzie at the helm, it just makes the deck that much better. Happy building!
