Wave-Motion Cannon is a fun card to play with, but it is very vulnerable to back row destruction. Therefore, plenty of Counter Traps can be used to help protect it. With the use of Counter Traps comes the use of the Counter Fairies that have effects related to Counter Traps.
The goal is to get as many Wave-Motion Cannon cards on the field, keep them there for a few turns, and then activate their effects to deal massive damage to your opponent. Use the Counter Traps and Counter Fairies in order to protect yourself and your Wave-Motion Cannons.
Have fun with the Counter Traps you choose to use as well as the Extra Deck monsters you choose!
