While it has been a faithful companion, your Companion Cube cannot accompany you through the rest of the test. If it could talk - and the Enrichment Center takes this opportunity to remind you that it cannot - it would tell you to go on without it, because it would rather die in a fire than become a burden to you.

Dark Ritual with buyback. I threw this in a random Warp World deck with great results

Card of the Day, December 19th, 2012
Mana Vault, it comes into play untapped and gives you three mana turn one. With a Voltaic Key it's a essentially a Black Lotus every turn except for 2 colorless mana. In that sense, I guess it's a lot like Sol Ring, except for the first turn.
For those of you who play MTGO, you get to play this in Cube Draft soon. And with fancy new art that's less like this Companion Cube, and more like an epic vault of mystery.

A broken piece of cardboard, like most mana producing artifacts from the beginning.

Voltaic Key is the key to this vault.

Not too bad even if you never choose to untap it.

This card is a dark ritual that can interact with artifact effects (Tinker) and the mana can be used on any turn after you cast it. PLUS it can be untapped for later use by paying 4 mana or through more interaction (Voltaic Key). I think you all know how good dark ritual is. This thing is dark ritual on steroids in the right deck, trust me.

Dream hand: 1 land, 1 mana vault, 3 voltaic key, 2 thran dynamo.
Turn one: play land, mana vault, 1st voltaic key, untap and reuse mana vault, play 1st Thran dynamo, play 2nd voltaic key, untap and reuse dynamo or vault, play 2nd Dynamo, play 3rd voltaic key, untap Mana Vault. Alternatively the 3rd voltaic key could be a doubling cube instead.
Turn two: Draw Emrakaul and play him from your hand (and still have one mana spare)!
In response your opponent then taps their one swamp and uses a dark ritual to play Diabolic Edict and you start weeping like a baby, while plotting your revenge...

New Dream hand: 1 Ancient Tomb, 4 Mana Vaults, 2 Voltaic Keys.
Turn one: Play Ancient Tomb, play 2 mana vaults, use them to play 2 more mana vaults and 2 voltaic keys, untap your used mana vaults ready for turn two.
Turn two: Use everything for 18 colourless mana (!) then p... (see all)

Time to make the spikes cringe!
How about some casual uses for those of us not intent on abusing fun but powerful artifacts?
Braid of fire is not a bad way to get repeat value out of both cards. For a cost of 1, you can transfer 3 from your upkeep to your main phase.
It also forms a nice two card combo with soulbright flamekin.
Turn 1: land, mana vault
Turn 2: land, Soulbright
Turn 3: land, something that can use RedRedRedRedRedRedRedRed
Playing this without a means to untap it is not worth it if you are planning on games going 10+ turns.
And now to go for broke: use black lotus to power out a Celestial Prism on the first turn!
