This Is the First deck I've ever built, I wanted to play Urshifu to try to take more prize against lost box and I can say it works (less or more).
I've chosen Arceus as my energy engine cause I think is more versatile than the lost box engine (in some game I've used more Arceus than the VMAX)
The hardest matchup is against mew and for that I was thinking on using Drapion V but idk
I really enjoyed playing this deck and I hope you like it. If you have some advice to improve my deck do not hesitate to comment
