This is a source of mana and card draw for a tribal deck, designed for my prospective tribal Commander featuring UB Rogues, RW Warriors, WBG Elves, and GUR Elementals. Since the Rogue, Elf, and Elemental decks already have plenty of options for card draw, I'd probably put this in the Warrior deck.

Every time I read a comment about "Well if this card had card draw/trample/haste/indestructible/hexproof/life gain...", I think "You're missing the point." They're armchair developer comments that fail to take into account the card's role in the greater Limited and Standard environment. No, it may not be as good as whatever card you're comparing it to. There's a reason for that. Not every burn spell is Lightning Bolt, nor does it need to be or should be.
PSA to everyone who keeps forgetting about the Reserved List:
You're on a website dedicated to talking about MtG. You're only a few keystrokes away from finding out what cards are on the Reserved List. You're also only a few keystrokes away from finding out why some cards on the Reserved List got foil printings in FtV, as Judge promos, or whatnot, as well as why that won't happen again. Stop doing this.
So it's a Vanquisher's Banner that drops the anthem in exchange for losing 1 CMC and becoming a mana rock. IMO, the mana rock abilities seem a little awkward here. Four mana is a lot to pay for a rock that only adds a single mana, so it's basically just window dressing. The card draw is the real star of the show here, and it could, quite frankly, stand on its own.
This card would benefit a lot from dropping the second and last ability and going down to 2. Otherwise, it is in a weird spot. As a 4 mana rock its laughably bad at color fixing. However, as a 4 mana "draw a card whenever you cast a spell" it could be the strongest version yet on an artifact with the others appearing to all be 5.

That card already exists. It's Pillar of Origins.
