Saheeli Rai deck help

Hi all! I leveled all the vanilla PWs to 60 and working on Saheeli Rai now. I'm having moderate success with this deck but I know it can be much better. Any help is greatly appreciated!

Supports
Thopter Spy Network
Shivan Reef
Drownyard Temple
Molten Nursery
True-Faith Censer

Spells
Exquisite Firecraft
Talent of the Telepath
Foundry of the Consuls
Uncaged Fury

Creatures
Runaway Carriage

These are some cards that may be good additions
Pia and Kiran Nalaar
Day's Undoing
Sanctum of Ugin
Sphinx's Tutelage
Brain in a Jar
Sigil of Valor
Claustrophobia
Molten Vortex
Call of the Full Moon

I'm unsure about what to put in or take out to make this deck good, I like the basic strategy with Molten Nursery and colorless creatures and supports but it's not working like it should
