He used 4 Lightning Spells as support, one to take out Clan Castle troops and the rest to destroy an Air Defense. The first person to have reached over 4,000 trophies (Jorge Yao) used an all-Dragon army to do so.This exploits the fact that dragons have a slow hit speed. However, you can use spread your archers and wizards in a semi or whole circle around the dragon. His high health also helps him survive attacks from even multiple Archers or Wizards (although a large group of either will usually be enough to destroy the Dragon). As a flying unit, the Dragon is completely immune to attacks from most ground troops, and his splash damage capability makes it especially suited for destroying groups of Barbarians and Goblins. Dragons are wonderful Clan Castle Troops.If the Air Defenses are too close together, a single Rage Spell applied to a cluster of Dragons can quickly wipe out all three. As a Town Hall 8 player, keeping your Air Defenses semi-spread while protecting them with Storages and other high hitpoint buildings is the key to preventing most 3-star attacks using Dragons.Multiple high-level Air Defenses are critical for success against Dragons. Dragons are one of the most powerful Troops in the game, and as such it can be difficult to defend against them.Be careful as these troops can distract your Dragons from attacking other more threatening targets, wasting time. Dragons will attack the Barbarian King and Clan Castle Troops that cannot target air units if these troops are the closest target, even though the Barbarian King and/or Clan Castle Troops cannot attack the Dragon or any friendly Dragons nearby.A level 4 Clan Castle can hold a Haste Spell which can be used to speed up the Dragons if time is in short. To prevent this, attackers should bring some Barbarians or Minions or save their Barbarian King to take out lone buildings in the corners it might mean the difference between a 99% 2-star and a 100% 3-star raid. When using mass Dragon raids one should be careful of Buildings in the corners because their relatively slow movement speed does not make it great for moving around from corner to corner.Dragons are mostly used to get Trophies and in war as their high cost doesn't make them great candidates for Elixir raiding.Which spells to bring ultimately depend on the layout of the defending base - an attacker should have a plan to destroy every Air Defense, whether that involves extra Balloons, Lightning Spells, Earthquake Spells Healing Spells, or Rage Spells.

Dragons can tank the Air Defenses and Wizard Towers while Balloons target the Defensive Buildings.

A powerful, but costly, strategy for Town Hall 7 and Town Hall 8 players (especially for Clan Wars) uses a combination of Dragons and Balloons.Then place a Rage Spell for mass destruction. Try to spread the Dragons along the edge of the base, as they will converge in the middle of the battle, when you have reached the base's center.

So using a pure-Dragon army with Rage Spells can be effective.
