An alternative can be this deck:

- Ice Spirit

- Fire Spirit

- Wall Breakers

- Gobling gang

- Skeleton Army

- Dart Goblin

- Goblins

- Skeletons

If you put those in the exact order, goblins and skeletons cards will be replaced by mini pekka and knight. If you follow exactly like in the video, you can counter anything in the event. With this deck I lost 2 rounds and won all 10 for the free banner.

You put Knight next to tower, and skeleton army to the bridge, but they must stay in knights rage.

Then put goblin gang and watch how you earn yourself a free tower, and the king tower too.
