You will need more protection though if you want to compete against the metagame right now.

Expensive yes.... I see great protection for your planeswalkers which is the key until your jace cards can do their best
That or get your Wild Pair out there as well.
Maybe add some more mana-getting creatures like Civic Wayfinder. I'm assuming that you are wanting to get your Shard Phoenix card on the battlefield as soon as possible.
I'm assuming you got at least a planeswalker in one of those boxes.
