back to Splinterland, first rewards

It's been a while, but I started playing Splinterlands again. What I didn't know was that the rewards system has been changed and now you get some chests when you increase in ranks.

This was the last battle that helped me go up (thank you mercystar). Also glad to see that you earn glint, which is a new system that I wasn't used to.

Here is what I received when I went from Silver 2 to Silver 1. I noticed that the small print says that the amount of SPS stacked influences the rewards, which is good.

So 9 chests as a rewards, not sure what the content of the chests can be yet, but I'll learn it.

I decided to use some potions, was this a good choice?

Not sure what to think of the rewards:

Merits used to be only be giving in guild battles, guess that changed. Not sure if the energy is of any help. The cards seem ok, but nothing special.

Anything I can do better?
