6Clash Royale card guide
Goblin Giant is a building-targeting tank carrying two Spear Goblins on its back. Since the goblins hit air, it has some protection against air troops even on its own.
Send Goblin Giant from the back and add support like Sparky, Dark Prince or Mega Minion behind it. While Goblin Giant takes the hits, Sparky charges up and clears the defense in one shot. When it dies, the goblins on its back keep fighting.
