[AER] Stormflux X Cheeri0s ft. Ornithopter Sram (Standard)

Another Paradoxical Outcome X Aetherflux Reservoir X Cheeri0s deck, but this time using some AER Revolt cards.

Goal of the deck : Cast Aetherflux Reservoir, put a lot of 0-mana card on the battlefield, get a lot of life, use Paradoxical outcome to get all the cards back + draw again a lot of cards --> Put more 0-mana cards, get 50 hp --> GG WP

Sram and Reverse Engineer gives some really great card draw.
Sigarda will help buff your Ornithopter and other bros as the perfect blocker with all these Cheeri0s.
Glint-Nest Crane as another reliable blocker, and quite reliable to 'draw' artifacts.
Baral's Expertise is a very well all-rounded tool, it can at the same time bounce the threatening ennemy creatures, bounce some of your cheerios back, and help cast Aetherflux Reservoir for free !

Deck building is still in progress, trying stuff :

• Disappearing Act instead of Metallic Rebuke
  Pro : No conditional counter, can bounce back an artifact to recast it for Sram draw or Aetherflux Storm.
  Cons : Expensive, 3 mana. More color restricted.

-Merchant's Dockhand instead of Glint-Nest Crane
Cons : Worse blocker than the bird, can't fly, can't dig an artifact on ETB. Expensive ability.
Pros : With all the artifacts in the deck, it's easy to scry 4 + draw with its ability. Great card digger. Is also 'Improvise Mana'.

-Aether Tradewinds as a sideboard card
The only card I found in UW against planeswalker. The drawback is not one, as bouncing back one of our artifacts able us to recast it.

Sideboard explained :

Authorities of the Consul : A blast against Saheeli Twins deck.
Fragmentize : Always useful in an artifact heavy sets, new aggro decks seems to use a lot of artifacts, useful against them.
Negate/Metallic Rebuke/Ceremonious Rejection : I'm always struggling on how to balance counterspell in a deck and sideboard.
Glint/Baral's Expertise/Ornithopter : Great card, maybe you'll need an extra of those.

( I'm not really good at building sideboard yet, any suggestions is welcome ! )
