Get Red Eyes Darkness Metal Dragon from joey pack for sure, how well do your cards work together? Their effects and your trap and magic cards should technically be working together to keep your monsters on the field, counter opponents effects, and destroy your opponents cards.
One of my favorite plays is to get Red Eyes Darkness Metal Dragon on the field along with Queen Dragun Djinn (Prevents dragons from being destroyed by battle) equipped with Dragon Shield (Prevents equipped dragon from being destroyed by battle and card effects) & United we Stand. Empty out the opponents magic card field with Tiger Dragon or Hieratic Sun Dragon Overlord of Heliopolis.
Mirage Dragon is also good to have on the field with Queen Dragun because he prevents traps from being activated during the battle phase.
My Hieratic Dragons help get dragons on the field for XYZ and Syncro summoning usually during MP2. And Red Eyes helps gets my level 5 and higher Dragons on the field (from my hand or graveyard) to XYZ summon Hieratic Sun Dragon Overlord of Heliopolis or another strong XYZ.
I also use Montage Dragon for a little brute force or when I'm in a tight situation. I also have some Galaxy Eyes Photon Dragon action in my deck.
Mine is WAY more basic than that lol. It mostly focuses on getting my high power dragons out as fast as possible, particularly the 3 Blue Eyes. I've got multiple cards that are used to get them onto the field via jand, deck and graveyard, as well as Azure Eyes and Tyrant Dragon (One of my favorites from back in the day) as the usual backup. Then there's counters to attacks, traps and spells thrown in, and I try to get a Golem Dragon with Dragon Shield of I need some defense.
