MTG Salvation

I'm planning to build an Olivia Voldaren-deck, and I need some way of storing up mana for future use. Is there an artifact or enchantment that you can put mana into and then retrieve it later?
The only card I know of that is even remotely close is Molten Slagheap, but that can only store one mana at a time. If I have a Braid of Fire on the battlefield I'd like to store it's mana too somewhere.

Gemstone Array. It's a 1:2 ratio, but it does work, and it can be used as color fixing in a pinch.

Black Mana Battery Red Mana Battery

I think Gemstone Array is the only one to store up colored mana in your colors, which you can store more than one per turn.

You can use Ventifact Bottle to store up colorless mana (that you have to use at your next precombat main phase). There's also Everflowing Chalice for colorless mana. Black Market get you black, but isn't exactly "storing up" your mana, rather you store up kills.

For adding 1 charge/turn:

• Altar of Shadows (you don't use up the charges)
  
• Black Mana Battery
  
• Bottomless Vault
  
• City of Shadows (you don't use up the charges, but you do have to exile creatures you control -- exile the ones you steal!)
  
• Dwarven Hold
  
• Kyren Toy (colorless, can be used as a normal mana rock, too)
  
• Lotus Blossom (one use)
  
• Mercadian Bazaar
  
• Red Mana Battery
  
• Shrine of Boundless Growth (colorless, one use)
  
• Subterranean Hangar

Oh, this is perfect! Thanks a lot =)

Black Market might also be of use to you.

Gemstone Array is my personal favorite. It also makes Ashnod's Altar into a Phyrexian Altar. It's just good in general.

Everflowing Chalice is a great one-shot deal that keeps on giving. Other artifact mana is similar, like Thran Dynamo or Worn Powerstone or Dreamstone Hedron. It is colorless though, so there's that.

Doubling Cube is one of my favorites, and if you've got stored mana you can start profiting big time.

Starting mana/ending mana with cube:
7:8
8:10
9:12
10:14
15:24
20:34
30:54

It just gets silly if you can copy or untap it also.

My favorite is Iceberg

Derp, cards already mentioned.

I think the storage lands are probably the only really decent cards for mana storage in these colors. You're better off just ramping harder I think.

Well, thank you for the two necros. I guess you felt we all needed to know the card Iceberg? It seems particularly relevant for this 6 year old request for help with a BR deck.
