No challenge so I'm taking for wild.

Necroforged

Sorcery

As an additional cost, sacrifice a creature.

Create a black artifact equipment food token with "equipped creature gets +X/+X where X is the sacrificed creature's toughness." and has "Equip " and ", : You gain 3 life."

"The necromancer chose to eat it and wear it."

Create a spell named "Winter is Coming". It does not have to be Game of Thrones themed.

This deck looks pretty good! It reminds me of an Urza, Powerstone Prodigy Unearth deck I was on the brink of building before The Brothers' War rotated out.

Only thing that I find concerning for your deck is the inability to deal with graveyard hate. If you were to find a spot for any combination of Karn, the Great Creator and Revoke Existence in your deck and/or sideboard that should do it.

Happy Hunting!

Chaotic Winnower

Creature- Eldrazi.

Devoid

Ward— Sacrifice a land or artifact.

At the beginning of each combat phase, Flip a coin.

If it comes up heads, creatures your opponents control with odd number power are shuffled back into their libraries. ~ deals 1 damage for each creature shuffled this way to any target.

If it comes up tails, colorless creatures you control with odd power get +2/+0 and Trample until the end of turn.

Create a card that makes you choose between odd and even.

Nickamos, Obsessed Poacher

Image: A Red bearded man, Nickamos, stands on a raft with a pole sticking into the water in one hand and the well cooked limb of a saproling in the other. In one corner of the raft lays a weapon. In the background, is the shore of a river delta.

Legendary Creature- Human Rogue

Swampwalk

At the end of the combat phase you may pay any number of times. If you do, exile that many target creature tokens and you create that many food tokens.

2/2

Wild

Billy Boy

Legendary Creature- Goat

First Strike

Sacrifice an Artifact: ~ gets a +1/+1 counter.

, : Shuffle your graveyard into your library.

3/1

Create a Legendary Creature with a four color identity. Three of the colors must be in the casting cost and the fourth must be in the activated ability.

Hey, mike6380! Thank you for the upvote!

Hey, Venum! Thank you for the for all the suggestions.

As I said on an earlier post I'm really iffy on monoblack cards. This is due to having Drowned Secrets and Sage's Row Denizen in the deck. I did, however really like the Eater of the Dead/Phenax combo idea so I'll add it if I find a copy inexpensive enough.

Mirko Vosk's triggered mill is damage dependent and Kraken Hatchling has the same toughness. Guilt Feeder would work well with Mindcrank, but Syr Konrad is the same mana cost. However, they both look really good so I'll keep them in the maybeboard for now to see if they grow on me further.

Thank you again for the suggestions and May you draw well!
