Typically, players with less than 500 trophies may worry less about attacks. When you reach enough, attacks become more frequent.
The higher number of trophies also means that the harder opponent is selected during the match-making process.

This is a video game that offers players the ability to create unique and complex Clash of Clans war strategies ... but we suggest that new players keep it simple. Here is a simple start strategy that uses the barbarians to defeat the enemy base.
Get rid of enemy mortar as soon as possible. The mortar has barbarians blind can take advantage of, which can not cover. Find this blind spot, take the mortar, and your barbarians take out the rest of the defenders.
Once placed units are no longer controlled, so place them close to the target. Each unit also has one unit, which rather attacks, but often attacks the nearest enemy.
