For sure. I got KOG with two gozukis. Didn't even bother with wyvern tbh. Bit more consistency with insight I suppose but it takes up space better filled by other things
I agree, Brachios shouldn't be in a REZD deck. Maybe take out for another insight and enemy controller, or for the original question, insight and wyvern.
youd be surprised. brachios benefits from straight to the grave and acts as inbuilt econ. several REZD got kog last season with brachios tech, including me (when rex was half the decks faced).
