Rattleclaw Mystic is an interesting rare from Khans of Tarkir, which will also be the buy-a-box promo for the set. Not only does it tap for Green, Blue, or Red mana (the RUG colors) but it is also a morph creature. What’s interesting about this one in particular is that besides playing it face-down for the usual 3 colorless mana, it only costs 2 to flip it. When it’s flipped face up, you add Green/Blue/Red to your mana pool.
The Mystic costs 1G to cast ordinarily, and that’s perfectly acceptable for a 2/1 that can tap for three different colors of mana. It’s not in the same neighborhood as Noble Hierarch, as that card is a single G to cast and this also doesn’t have Exalted on it – which matters more than some people realize. It’s a slightly worse Sylvan Caryatid as it doesn’t have Hexproof, but it also doesn’t have Defender, and does have the surprise factor to be able to generate 3 mana upon morphing. Also, if it’s been on the field for at least a turn, or has been given Haste, it can then tap for a fourth mana upon morphing.
This Mystic can trade with creatures if it has to, which is a plus in some people’s minds, but I’m not sure why you’d want to. It also is yet another ramp card that can color fix if there are meaningful spells requiring RUG mana. This is a very good card in Animar, Soul of Elements EDH decks already, as well as Riku of Two Reflections, and Intet the Dreamer decks that occasionally are just missing the one color (or even two) to cast their Commander. This might see competitive play if RUG decks become popular in Standard. It will be interesting to see if there is a “mana dork” for each of the clans.
It’s no Sylvan Caryatid and is slower than Voyaging Satyr in ramp decks, but I think this Mystic will find a home in Standard and definitely a few homes in EDH.
