I was also thinking about Coalition relic instead of manakin. It fixes your mana, may give you two mana, maybe more with Voltaic key, you can also use the charge counter with Power conduit to turn it into +1/+1 or add charge counters for more mana.
Aura finesse is useless you don't play any auras.
Tidings is strictly superiror to Jace's ingenuity.
Try Rift bolts, they're a good substitute for lightning bolts.
A lot of your creatures don't have any synergy with the deck, cut them.
Try to have 60 cards in your deck, it's better that way.
You could cut two FoF for the planeswalkers if you want.
Staggershok makes your creatures trigger twice so they're pretty good.
Try Ancestral vision if you can afford them.
Hope that helps.
Academy Ruins could fit in your deck, as well as Gilder Bairn.
I would play with four steel overseer.
Also maybe Chainbreaker?
Mindless Automaton for draw?
Consider Honor of the pure.
Maybe path to exile instead of wing shards? You don't have any ways of abusing the storm.
So -2 reciprocate, -1 humility, -1 crusade, -4 Wing shards, +4 honor of the pure, +4 path to exile.
EDIT: Try using Empty the warrens for extra fun.
There's also Pyromancer's Swath to combo with grapeshot.
He has temple garden and hallowed fountain both are plains.
Here is how I would do it:
4x Kiln fiend
4x Wee Dragonauts
4x Gelectrode
4x Tidings
4x Fact or fiction
Burn
4x Ligthning bolt
4x Rift bolt
4x Incinerate
4x Fireblast
4x Staggershock
20 lands
