This is the first Pokemon competition that not only has my preferred battle form (singles) not only have I thought about EV's and IV's, but I think I might actually have a chance of doing well! I call this team of mine...

I haven't come up with my own movesets, I have got them from different webs, but I have edited some of them to my liking and to fit the rules of the competition. This team is a Hyper Offense team focused on the OHKO and have a variety of coverage moves. This team is also capable of having different leads as well as supporting each other in battle. It lacks walls, but I think it can manage because it has a strong defensive core. It is designed to counter some of what I think will be common Pokemon in the competition. Regieleki's role is a counter for Gyarados as I think a lot of people will be using it. Gyarados' role is the lead Dynamax sweeper and can support its teammates with its Max Moves. Flareon's role is a defensive/support Pokemon who can support its teammates with Wish/Baton Pass, while also delivering hard hits. Thanks to Trachy for this moveset! Ferrothorn's role is a wall for most Pokemon in the Crown Tundra Pokedex. Dragapult's role is also a counter for most of the powerful Pokemon in the CT Pokedex, and it's able to take down Garchomp, one of the Pokemon I fear the most in this competition. And finally, Lucario, a Physical sweeper with a variety of coverage moves.
So, all in all, this is in my opinion one of the best teams I've put together. Never Fear! THE TUNDRA HEROES ARE HERE!
