Psionic Draw Combo OTK

First draft of a deck i was inspired to build after playing through the Draw puzzles.

The combo is getting 0 cost Second Sight into your void, then you top deck it with excavate then use Elysian Trailblazer to give it echo. Once you have those in hand you just need to slap down a Psionic Savant with charge given to it with Accelerate play the 0 cost Second Sight top decking the other one, then keep looping the 0 cost second sights until Savant has however much attack you need to kill your opponent. Can also do it with Baying Serasaur though lack of flying means it is too easily blocked.

No the combo isn;t super consistent but it is fun to pull off. Would love advice on things i haven't considered or ways to make it more consistent while also managing to survive until you can pull it off. Also the market can do with an overhaul, though i like Maul as an alternate win con.
