I made it my personal mission to take cubics to the highest rank of the master duel competitive ladder (I’m a masochist i know). I am currently in gold 3 and even though I’m not hard stuck I am having some trouble and can see that my deck needs an upgrade. I have been running pure so far but I’ve been considering including either eldlich or dogmatika, which one is better for my deck or is there something better that can help my deck climb the ladder?
