I just think how about if supercell launch events monthly winning them we can get gems, de, upgrade card, or speed up cards etc.
In the event supercell will give some task complet them offer us some rewards.
These tasks can be:-
Win battles 10,20 or 50 something
Donations 2k to 5k
Gold,exilir and dark exilir loot
War stars
Win 3 Str battles and continues battle
These all tasks are enough to keep player busy whole month and for achieving gems everyone will play the game.
