I will upload a video of combos and strategy eventually, with an in depth guide to each Dogmatika card.
In short, this deck wants to go first and setup a variety of different boards depending on the cards you open. Generally, you want your Rituals to snipe your opponents extra, or your fusions to interrupt your opponents plays.
Side Deck consists of going second cards to break boards. They are generally considered weaker because they only have utility going second, but if you know your opponent will go first, then they are a good side deck choice.
