Until now, your only choice was Supreme King Dragon Darkwurm. Supreme King Z-ARC has the power to Special Summon a Supreme King Dragon from your Deck or Extra Deck, any time it destroys something in battle. Finally, Code of the Duelist is bringing the final Supreme King monsters, the DARK variants of the Dimension Dragons themselves! Then, Pendulum Evolution gave us new Magician Pendulum Monsters and Astrograph Sorcerer and Chronograph Sorcerer to get Z-ARC into play even easier. It was tough to use at first, since it needs four Dragons as its Fusion Materials, and they need to be one each of Fusion, Synchro, Xyz, and Pendulum. In Maximum Crisis, we first saw the awesome Supreme King Z-ARC, a crazy strong Fusion Pendulum Monster.
