Revolt Rally Scions (Standard)

Thought process in creating the deck-

Q: My thinking started with "what is the simplest way to trigger revolt?"
A: Scion tokens. (My first answer was clues but they cost 2 and scions actually get you a mana, so they win.)

Q: So big whoop, you can activate revolt on curve in standard, so what else goes well with this strategy?
A: What if all the sacrificing did something other than just trigger revolt. Well, Rally was a pretty awesome deck. Standard parts that remain from old versions are Zulaport Cutthroat and Catacomb Sifter. Other older versions played Smothering Abomination.

Q: Ok let's go all in. What other sac outlets are available that are useful?
A: Ayli gains me life and this deck is not a super fast deck. Yahenni is a decent creature to test out as an indestructible blocker. Voldaren Pariah is a great alternate wincon.

Q: I have a couple slots left. What is the deck missing?
A: Rally the Ancestors. No wait, Collected Company. JK. Something that repeats would be nice. Scrapheap Scrounger it is.

Sideboard is pretty solid. We deal with all the threats pretty well with answers for aggro, board wipes, planeswalkers, control.

The deck may have too many sac outlets and not enough protection. Just needs some testing to see how the balance fairs.

I'm impressed with the amount of removal for a deck that plays very few noncreature spells. There are 10 removal spells and 5 deathtouch creatures. Only five flyers in the deck and not a lot of answers for Avacyn. Worries me a bit.

Overall the deck will be a fun challenge to play. Turns will need to be planned well. When do I sac my creature? Do I chump block now? What do I do against decks playing Gearhulk's?
