Take damage, your Opponent also takes damage.
Strategy: I'd recommend going either first or second with this deck as either works. For your Early Game, get up your Rockruff's, Snorunt's, Munkidori, and maybe Maractus. Then get Maractus in the Active (if possible), or just use TM: Evolution. Froslass helps spread damage and Munkidori can move more onto them, Maractus when KO'd, can get even more Damage onto them and with Vengeful Punch can place 100 damage onto them! Lycanroc can get 2 Spiky Energies from your Discard Pile onto it which can also deal a good amount of Damage to them and increases its attack's damage output further. Jet Energy is helpful overall as it can Pivot you into another Pokémon like bringing in Bloodmoon to swing into the Active for game, or like bringing in something like Maractus to then attach TM: Evo to evolve your Pokémon. Now the ACE SPEC of choice, Unfair Stamp, is an excellent choice in this deck due to its Disruption letting you get 5 Cards and your Opponent gets 2 Cards which can slow them down a lot. You could run Precious Trolley, Neutralization Zone, or Legacy Energy instead though. Morty's Convtiction is a neat card as you could potentially draw many cards. Also, Lycanroc ex, is another backup attacker that can help get 100 Damage onto your Opponent's Pokémon when damaged in addition to the 140 Damage it does doing 240 total and a bit more if you attach Spiky Energy to it. That's all I have to say about this deck so feel free to make any changes or to leave any suggestions! This deck was suggested by @Waffle Enthusiast.
