Hello friends. I previously posted maxed level decks for silver and gold leagues.
Here is a Dragon deck for you to consider.
I chose Kretch being the cheapest summoner. Quix is also good but I don't like his abilities that much. We will have a choice of Djinn Chwala (Thorns) or Void Dragon (Void) for our main tank followed by Carnage Titan. This will be supported by other cards from the other decks. You may also consider neutral cards like Supply Runner.
This completes my list of maxed deck for silver and gold league. Have fun building your deck! 😀
