Electro Giant is a powerful building-targeting tank that zaps back troops attacking it. Troops attacking it at close range take damage and get stunned.
Send Electro Giant from the back and use Tornado to pull enemy troops next to it; everything that attacks it gets shocked. Add Bowler, Electro Wizard or Lightning behind it to break the defense. It's very dangerous in double elixir.
Tips
Use Tornado to pull defenders close to Electro Giant.
Its reflect resets an Inferno Tower beam.
It's expensive, so wait for the right moment instead of playing it at the start.
Strengths
Shocks troops that attack it, making defense hard.
A very sturdy tank.
Weaknesses
Very expensive, leaving you open in the other lane.
High-damage cards like P.E.K.K.A and air troops can stop it.
