The Best Colorless Mana Accelerator I Know Of

I have had Palladium Myr in my Commander deck going back to when I first pulled one from a pack.  At the time, I had been working on my Silvos, Rogue Elemental deck (back when it used to be called EDH and not Commander format), and mana acceleration was on my mind.  There are few cards that can match offering 2 colorless or even colored mana for a casting cost of 3 mana.  I have this one in my deck along with Greenweaver Druid, with cast cost 2 colorless and a G, and it returns 2 green mana.   Fyndhorn Elder is also essentially identical to Greenweaver Druid, and thus like Palladium Myr.  The only detraction I see for Palladium Myr from the vantage point of my Commander, Silvos, Rogue Elemental is that he isn't an Elf, and thus Palladium Myr doesn't really fit with another 5 star card like Priest of Titania.

Review of Star Compass **** Great for Multicolor Decks!

To pay 2 mana, especially colorless mana, in order to get 1 mana, as an activated ability is a good deal. But, that this card is an artifact is an added advantage. That is, in my opinion is more difficult to remove an artifact from the board, than say an elf creature. Most mana accelerators are elves, and they don’t have much toughness, so they are easily dealt with. Elves also require green mana, which can be more difficult if you are playing a 5 color deck, for example. Since given certain circumstances that this card can tap as any color is another reason it is great. A card like this is best combined with a multicolor deck that has a card that can untap it. That way, it can be used twice on the same turn. What makes this card fun is that it can be worked into multicolor deck very easily.
