It's a shame that I got 7th place this round 😕

I thought I would be in 4th place. But, it wasn't. What a shame 🥲 My snow ball didn't grow much this round. The point gap between me and the 1st place is around 600 🤔

I assume Summon tickets are better to earn points than Reroll tickets

Let's make an example.

If you got total 4 stars cards, you want to reroll cards to get more than 5 stars cards.

4 stars cards mean the sum of attack damages is around 30+30+50 ≈ 110(Including bonus damages)

Therefore, If you reroll cards, then you get 5 stars cards. The sum would be around 140 ≈ 30+30+80. It only increases 30, and you used 30 points.

But, when you use Summon cards, you use 50 points, and the expected value of sum of attack damges is above 90 ≈ 30 + 30 + 30

So.. I feel the expected value of Summon cards is a little bit higher than Reroll cards. But, if you perform daily quests well, the result might be different.

I just wanna share my thought and gameplay strategy. It could be not the correct answer.
