How many QQ magic cards does it take to cheer for the World Cup?

Seven is not enough. It should be 27+27+24+6=84.

First of all, there are six kinds of material cards.

When 40 denominations are synthesized from left to right in the first round, the number of required material cards is 844,332 respectively.

These add up to 24. However, when 40 is used to synthesize a card with a face value of 150, the first card with a face value of 40 needs two cards, and the first card consists of 1, 3,4 (from left to right). So we can synthesize 40 cards from material cards, then 150, and then 24+3=27 cards with a face value of 540.

Then, after this round, only 540 cards are produced from 27 cards. The next thing you need is a card that refines 150, which requires another 27 cards; After this round, you have a card with a face value of 540 plus three cards with a face value of 150; Similarly, you need to refine the face value of 40, and then you only need the material card of 24. Finally, add the original 6 material cards, that is, 84 cards calculated above.

The number of sheets required for each material card is from left to right: 2713151397.

I hope it helps you. I'm also practicing this deck. You can change it when you have a chance.
