We all generally have an idea about what a "Good" "Something" is. It's not perfect. But it is in the general direction. If a car is a terrible design/engineering project, most people can see it immediately. The real expertise is for going from the general direction to bull's eye. I'll open the article with a quote from a great piece of writing from 
Learn From Successes; Not From Scratch
Recently I came across a very good moment to show the beauty of this lesson while instilling more confidence in 
Above is part of the result of opening two Booster Packs. The Legendary Card you are looking at is worth $12.63 and I only paid a $1.71 for the entire Booster Pack (bought from STEEM-Engine) I play Gold League and another thing to notice is that beyond Bronze League, the card is not badass.
Time For Stats
A max level Javelin Thrower is worth as much as a single Spirit of The Forest. But at the start, the Legendary Card is more powerful. Then the Rare and even Common ones become more extremely competent. Then you have some extremely valuable ability for leveling up the Legendary Card. This is game design at its finest.
- Getting a Legendary early is extremely rewarding.
- More Packs/Orbs/Rewards(Quests) you get, the more likely you are to get a Legendary or encounter an opponent with a Legendary card.
- Leveled Up Common/Rare Can Make up for lack of Legendary Cards. Things do't look Pay 2 Win.
- Level 1 Legendary Cards are mostly useless in Gold League.
- Level 2 & Level 4 Jumps are the most rewarding.
- There is a massive incentive to grab 2 more Legendary Cards of the same monster/summoner right after getting the first card.
- There is also a considerable incentive to get 6 more Legendary Cards to reach Level 4
This is Great for Market Value
It's the smart choices like this that makes me trust the future of a project. Every right incentive adds up to build a large ecosystem while creating price floors.All of these cards used to e much less valuable few months ago. Your money was truly better off on some virtual cards than some stocks or bonds. You are also seeing the birth of a game that is being well designed. These are the bull's eyes I talked about.
You can have you entertainment and you can review products. But you can also learn from them on how to do things right. If you feel in the gut that a product is doing something clever, then there is probably something very right about it.
