Buying cards from market is little bit confusing because the price is not fix for any card. everyone can list cards at their own price.
So if you need fans and looking for which cards you should buy?, the best answer is rare cards from peoples category.
Why......????????
Because mostly rare cards from peoples category contains fans and skills.
skills are very important keep ego at 0% as much as ego will increase the starbits reward will decrease.
Rare cards are cheaper than common if you will compare fans and skills.
Rare cards in peoples category have some awesome combinations of fans and skills some of them also have luck and IM.
You can choose any which is fit for your need.
Why Rare cards are better than common.
let's first talk about common card.
go to the market and check the price of common cards.
mostly common cards price range is 1000 to 2000 starbits (its just a range price,it maybe lower or higher).
Let's suppose If we buy 10 common cards(37 Dennis) with 15 fans at the price 950 starbits each, the cost of total 10 cards will be 9500 starbits and we will get 150 fans.
on the other hand if we will buy a rare card(R70 Jamie)
it will cost 8399 starbits and will give 125 fans and 100 skills.
its 1101 starbits cheaper than 10 (37 Dennis) and only 25 fans less, also has 100 skills. whereas 37 Dennis has no skills.
See one more example of common card.
32 Leaf is listed in the at price 950 starbits for one cards.
if we will buy 10 cards 32 Leaf at the price 950 starbits each they will cost us 9500 starbits and we will get 100 fans and 20 skills. on the other side R75 Greg listed in the market at price 6300 starbits. which will give us 100 fans and 150 skills.
R75 Greg is 3200 starbits cheaper than 10 (32 Leaf) cards.
I suggest you to do better research before buying cards.
