The most new Players Put the Giant wrong so they can't build up a huge push. If you play a deck with Giant Put him behind your tower. But first wait until your Elixir is at the start of the Game at 10 Elixir.
Let's start our push. If the Giant reached the bridge put down your Mini P.E.K.K.A for example. Put it behind your Giant so he can tank the tower damage.
If your Giant is still at live push more and more with other minions.
If you want to defend don't try to defend on your opponent's site. If you defend on your site, you deal lot of more additional damage with your Arena Towers and King’s Tower. For Example a Musketeer is near your tower. Wait until your tower is attacking the Musketeer then put down your Musketeer and kill it faster with the additional damage from your Tower. This is very important to get an Elixir advantage.
If your opponent put down some Archers and they reach the Tower don't panic. Sometimes it is better to take a litte damage and let your tower deal with small troops. Save the Elixir and counter with your next push.
In Clash Royale Elixir is most important without Elixir you can't win the Game. To get an Elixir Advantage it is important to know how to deal with the troops.
If you lose a game try to think why. If you using a good deck from any pro player try to think what was you mistake and look at your game replay. Of course sometimes you need to play fast but think about your play and think into the future how to counter. If you stuck a long time try to use another deck or look how pro players play at youtube.
