You may want to consider adding in some of the red 'card draw' effects like Outpost Siege and Vance's Blasting Cannons  ^Flip since red can end up with a lack of cards in hand in the late game.

Commune with Lava is another really good card to get yourself some new options for a turn.

Endless Atlas will be card draw for you since you are running mostly mountains.

Tectonic Reformation can turn any mountains you draw into card draw if you ever just need to try and dig through your deck.

Lastly some wheels could be good options like Khorvath's Fury and Magus of the Wheel

Warstorm Surge is another burn on entering the battlefield effect for your deck.

Since the deck is also 11 cards short I would consider adding the cards listed above as well as some more mana rocks like Fire Diamond , Mind Stone , and Wayfarer's Bauble .

I really appreciate this bc ive been struggling to find some red card draw. Thanks for the help!

Ihappen to really like going in a heavy artifact direction with the purphorous deck (artifact creatures or artifacts that make tokens), and including Myr Incubator . if you can exile 20 artifacts from your deck you'll win on the spot.
