(As was the case with Tarmogoyf there.) If I count this as a noncreature spell, will I still have enough creatures for the tribal cards in my deck to function
Here, since you have to tap to use it, and you only have 6 uses, I like it with haste in Red or equipment, untaps or haste like Thousand-Year Elixir and then after it's done, a blink effect like Momentary Blink
The deck revolves around casting an army of spider creatures and then using Shelob's ability to give your entire army deathtouch, ward 2 and most importantly effectively resuscitate your opponents' creatures as tokens
For example, if you control Elsha of the Infinite ("You may cast noncreature spells from the top of your library") and Keeper of the Crown is on top of your library, you can cast Coronation of the Wilds, but not Keeper of the Crown
Kaima is even able to extend his magic to Chishiro's squadron
