Here, you can challenge any players that you want to attack his/her village.. if he/she accept your challenge you will be able to attack just like revenge..
-if you win, you will get some rewards of resources.
-if the player who accepted challenge can defend, he will get 3 to 5 gems.
-you can only challenge the player whose traps you have not seen last 3 days.. like you cannot challenge same clan's player or player of a clan you just left..
-you can challenge and attack without breaking shield!!
WHY THIS IDEA?
- for reducing the boringness of just 50 single player mission.
-for testing your skill...which will be good for war
-for experiencing the needness of good village if you are challenged by another player...
Recap: You can only attack if he accept challenge.. if he doesnot reject or inactive, challenge will be removed auto after 48 hours..
