2Clash Royale card guide
Goblins are a very cheap, fast-hitting ground swarm. They deal huge damage for their cost, which makes them great for killing tanks and for sudden tower pressure.
On defense, surround single-target cards like Mini P.E.K.K.A, Prince or big tanks. On offense, send them straight at the tower when your opponent doesn't have a small spell in hand. In cycle decks they help you win elixir trades.
Cards that deal with it efficiently:

This card has a hero form. The hero is active in your deck’s 2nd (Hero) or 3rd (Wild) slot. The Hero slot unlocks at Arena 5.
ElixirDeck automatically takes your unlocked evolutions and heroes into account: build your decks.
