This is my updated Gammamon deck. Note that the RB1 Regulusmon is a placeholder for the new Regulusmon that was revealed the morning that I posted this. It acts as a new boss for the deck while also being a strong finisher. The new Gulus is strong when it comes to looping your Regulusmon which helps increase the decks potency. I no longer run as many of the older Gulus but I still run a single copy of the RB1 Gulus because of its end of attack effect being pretty strong still. Especially when used with certain combo lines. This deck is extremely combo focused and plays in a midrange style. Use your cards carefully and try to adapt to what your opponent is doing. There are a ton of different lines to the point where even explaining them would get me over the character limit here. I've tried and failed to fit them all in. If you want to play Gammamon there are easier builds to pilot but this one packs a ton of power. And in case you are wondering why I am running a single copy of Siriusmon Ace and not Arcturusmon or even Proximamon, it's because I find those two cards to be a little clunky if not even useless most of the time unless you build the deck around them. I built this deck around the Regulusmon half of the deck which means I approached it in a different way than the build up a stack and beat your opponent down with it type of game plan. You can very much remove the Regulusmon cards and run Canoweissmon instead. Those are aggressive but more straight forward if you play them. But they lack the depth and complexity that I like.
