hello do someone know how big the change is of getting a collection card from a present box D?

well last 2 weeks about 1400 holes played and 4 cards.... a friend had 4 cards on yesterday only
In other words...its very random

After collecting 248 Present Box D during the event held not long ago, 39 contained collection cards (so anywhere between 14-18% appears to be the drop rate). Mine drop rate was 15.7%

In the 248 boxes I found:

42 Nepenthe
39 Collection Cards
29 Mopsos S 9
21 Various Tornado S 18 clubs
20 Rosemary Nectar
18 Various Tempest S 18 clubs
18 Clothes Combining Ticket
14 Zodiac 18
14 Various Hurricane S 18 clubs
9 Action Nectar
9 Cyma S 9
9 Mageia S 9
3 Zodiac100
3 Various balls

Of course these result are affected by general standard deviation and should not be interpreted as very accurate percentages.

Hope this help?
