This deck is a high-risk budget deck made to smack your opponents with Phylactery Lich. I tried to find and use cards that are less than $1

Find the Phylactery Lich

Dark Tutelage : A lot of the cards in this deck are under three mana with the exception of Diabolic Tutor, so this card can help speed up the process of finding the lich.

Diabolic Tutor: When you just need that lich in your hand pronto!

Read the Bones: The scrying is nice to weed out the cards you don't need.

Sign in Blood: Cheap cost for two cards.

Keep Phylactery Lich on the Battlefield

Darksteel Axe : Cheap, indestructible, and gives a nice +2/+0 bonus.

Darksteel Citadel: It's an indestructible land. Nice!

Ghoulcaller's Chant : In case you're facing a deck that counters or sends your liches to the graveyard.

Weapons

Phylactery Lich: The reason this deck was made. It costs a mere three mana, it is indestructible, and because you are using darksteel artifacts there should be no reason for it to die at all. Except for things like exile.

Swiftfoot Boots: Oh wait, don't worry about the lich being exiled when these boots give haste and hexproof on the cheap.

Avacyn's Collar : It's cheap to drop on the battlefield and it gives power and vigilance bonuses.

Inquisitor's Flail: Since the lich is indestructible you can let it flail around wildly with this equipment with no fear (word play intended). Remember, if a creature has more than one equipped, the damage can increase to fourfold, eightfold, and so on!

Vampiric Link : It's a cheap enchantment that can bring you back up in life in case Dark Tutelage took it's toll a little to hard.

Worldslayer: Because it's hilarious.

Other Considerations

Stir the Grave : Maybe you want to bring the lichs back to the battlefield for cheap.

Executioner's Hood : Make your lich unblockable with intimidate if the opponent has a lot of chump blockers.

Hot Soup : Like the hood, it allows your lich to not be blocked. It's also cheap, and it's drawback is negligible since the liches are indestructible.

Imp's Mischief: Because it's funny.

Lashwrithe: A free creature with a big weapon because of all the swamps.
