With the printing of Gigantosaurus, Thrashing Brontodon and Steel Leaf Champion the deck has evolved from good to very competitive. Anyway, give it a few play tests if you are interested and let me know what you think.
With veteran explorer I know that I 100% will not enjoy a 30 minute grindfest against someone who can barely afford dual lands and believes that their deck can cast a 10 mana 8/8.
