It's time to buy cards and do a small test!
(P.S. this test is just for personal fun, don't TAKE IT SERIOUS:P)
I have bought 50 Lucky Star and here is the result:
Silver:162
Gold:78
Diamond:10

Legend:0

This cost me 124900 coins.
After sacrifying all 250 cards I got, I will get 3204 rubies.
With the reference of the price of Large Coins Chest, 124900 coins approximately worth 380.46 diamonds.
Which means that 1 diamonds can give me 8.42 rubies per diamond with method of SACRIFYINGThen I look at the price of Pile of Rubies......12.5 rubies per diamond.
OK. I just have to admit that I have bad luck. I should have had more Diamond Cards and Legend Cards if I have done works of charity


P.S. Can ECB add back the BUYING DIAMOND CARD system please? I have joined this game since V1.6 and I couldn't buy diamond card directly. Compare with the Lucky Star Pack, I love the old system more since it can guarantee me more diamod cards so that I can at least, have more strategies when battling. Although without diamond or higher level card, it is still possible to enter 100th ladder, I want to have more kinds of card so that I will enjoy playing this game more. THANK YOU=)
