Rise of the Eldrazi delivered some new Kor cards to further add to the theme. Worldwake left me wanting more and made my deck go into hybernation. However, this new set gave the deck a whole new spin on how to run their equipments. Up until now, Kor decks focused on using their artifact equipments to gain strength, but no more. One card changed it all...Kor Spiritdancer.
Kor Spiritdancer has now opened the door for a whole new arsenal of weapons to the Kor in the form of Auras. However, since this is the only Kor that is meant to work with Auras, it doesn't necessarily turn the entire deck into one that depends on Auras. However, even though Auras work similar to equips in the terms that they provide boosts to a creature, they are still completely different. So your Armament Master won't gain anything from an Aura.
The benefit of using Auras in Kor combined with this card? Some of the new aura cards have a low mana cost and can work great with the Kor theme. So even if you have a Kor Duelist equipped with everything you need, an Aura could give it that extra boost you need to get the job done.
Not only that, using Auras along with Spiritdancer can give you a slight draw engine if you think about it...
Just sharing a few thoughts on another card I found interesting...too bad it's a mythic rare.
