You may have noticed the different Merge Dragons Dragon Types!
Zoomer, Harvester, Builder, Defender, Worker and Trophy are the various Merge Dragons Dragon Types.
What does this mean?
Your dragon will move faster than other Dragons if they are a Zoomer.
Harvester Dragons harvest quicker than other Dragons.
If Zomblins or Decayed Wood appears, the Defender Dragons will destroy them faster.
