Let's make this report backward.
No upgrades to report to.
I've got these rewards. Cards, potions, DECs, ...
Legendary Spirit Miner and 1200 DECS were the highlights.
The new look of the rewards page before opening the individual items was a nice surprise.
These chests look like they have teeth. Intentionally so, I presume.
Seven matches stretched across two hours sufficed to finish a Dragon splinter quest.
Before ending the quest I've climbed into the Gold II zone.
That's a start :)
Better and better
You are lucky. I have not received cards for the latest season end rewards.
I have received only 3 Alchemy potion charges, 33 Dark Energy Crystals (DEC) and 1 Legendary potion charge.
That's a bit too biased in the new direction, I agree. Hopefully you've got some decent cards by now.
