I think Splinterlands' daily quests for beginners(Novice and Brone III where I mainly play) are well designed. By completing the quest you learn many different aspects of different cards, skills and strategies.
For example, Death quest, Life quest gave me a chance to navigate through these cards. Before then I used to mainly play with Fire but could experience and learn. And it is good not only for training new cards but to understand how it works so that think an appropriate strategy when the opponent pick these cards.
Now I am working on Sniper quest and this makes me better understand how this skill works! And I keep thinking and moving around the card to build the combination best works for me.
Well made game and well made quests!
