make sure you have high level heroes if you're going against maxed defenses so the attack will work.
The name of the attack is GoVaHo or GoVaHoLo (if you're adding balloons as well). Hope you like it, comment in the video if you do (or have any questions), and don't forget to like and subscribe as well (it helps a lot!! so thanks to anyone who already doing that).
Also, make sure to check the video on blasterzone (so you can zoom in and out inside the video). here's a link:
