MTG Salvation

Alela, Artful Provocateur/Kykar, Wind's Fury

Kykar is obviously more abusable if you want to play control and storm, though Alela comes with natural creature buff and herself is more "Voltron-ready" than Kykar. Alela also has black instead of red, which gains her access to more precise tutors as well as reanimation.

With a bouncing black enchantment from Urza's block, Alela could also shut down opponents with Contamination since she produces tokens when you cast artifact/enchantment. I've tried to make an aura-kykar deck, it appears Alela might be better in this regard with her aggressive stats and all the faerie supports.

Alela

1. Access to black.
2. Creates token via artifact/enchantment.
3. Creates faerie and is a faerie herself.
4. Buffs flyers.
5. Three combat keywords.

Kykar

1. Access to red.
2. Creates token via any noncreature spell.
3. Creates spirit.
4. Can sacrifice any spirit for R.
5. One combat keyword.

Kykar seems more powerful, not only can produce tokens at instant speed, it's a sacrifice outlet that generates mana, it's more wide because you can play storm, artifacts, anthems even superfriends, Alela only generates tokens with permanents.

Alela seems more like a Stax kind of card. Both are good in their own right though
