Runed Halo could give you protection from pyrohemia.

The theme of this deck should be to mana ramp to zacama and use zacam to control the game. Once zacama is out the focus should be on getting to an enchantment that doubles your mana. Drawing cards and tutoring are the best way to get there. Fierce empath should get wakening sun's avatar for a non dino board wipe and a win. Tooth and nail should get regisaur and gishath. The enrage abilities are there a secondary win condition. Making those dinos indestructible and enraging them will win you the game. Commander damage will probably allow you to start knocking people out.
