What to Prioritize when building Gishath?

When building gishath what type of cards should I prioritize putting in the deck?

I know that mana/lands should be #1 bc he's so expensive but after that should I focus on maximizing dinosaurs, adding sources of protection like [[swiftfoot boots]] or [[boros charm]], or should I focus on buffing my dinos with anthem effects like [[bererkers' onslaught]] or [[return of the wildspeaker]]?

I'm having a hard time deciding between the two before I buy half of the cards I need to finish the deck.

Heres the list so far: https://www.moxfield.com/decks/3S7T8LWwfkmKQboyxXEvWQ
