Season Rewards + Daily Reward for 4.15

Today's daily quest was to win 5 battles using a monster with the Sneak ability.
It took me ages to get it done this time. I didn't use a strategy for it really, just picked a Sneaky monster whenever I had enough Mana available to do that. I mostly prefer to avoid using Sneaks in low Mana cap battles, and unfortunately I had a lot of those today so that dragged the quest out a bit. It seems that with the new season starting, our Rating has been reset. I think that may have contributed to the quest taking so long to complete since it seemed like I was matched with more players who had more leveled up cards and Legendary cards than usual. Might have just been bad luck. Either way, I did eventually manage to complete it after a few long losing streaks.
My prize was a new Legendary potion -

I do wish we could sell these or trade them in for something else. Mine are stacking up, and I don't have any immediate plans to buy any more booster packs soon.
I had better luck with the Season Rewards that we were given today. I had 7 Loot Chests to open and this is what I got -

My first Gold Foil card!

It's worth about $1.50 on the marketplace right now. I don't think I'll sell it, though, it's surely more profitable in the long run to keep it and use it as often as possible. It's an Earth splinter monster, and that's one of my favorites to use, so I'm sure it will get plenty of use.
