I've been using the set I built myself and now it's a bit difficult to play.

The highest I can reach is 8400. You can take it without any thanks. The screenshots of the results are below. This is my main deck. The winning rate is not bad. It will definitely be no problem to hit 7500. Above 7500, please see the operation and card understanding.
The other side of dreams
Is the average cost of your set too high? It is easy to not get core cards or defensive cards with double the cost.

Let me give you a self-made deck of 8,000 cups for overriding.
