This is my attempt at Explorer Dinos. The main theme of the deck is the Evelina + Explorer combo to ramp your lizard overlords. Killer is more or less in the deck to serve as board control alongside the spells.
Main Targets for Ramp:
Ila & Mizo - Gets their mastery quicker, meaning more of her, which is never bad.
Frenzied Omnivore - This thing only gets stronger as youre enemy units die anyways. But if you can ramp and afford his killer cost, its a nice avenue to help control the board state through sheer force.
Avisaur Patriarch - Besides already being the best support card in the deck, make it more threatening by making it bigger.
