Yes you can get it easily you can get the apk easily. Even there are some apks that will give you the free resources and th10 war base anti everything so its not a big deal to get clash of clans off the google play. If you need any help you can ask me.
Did you play clash of clans if yes then please add me to your clan. I didnt tried clash royale so i have no idea about it. Even i am planning to play their games of super cell like the new games they had launched.
