Mad Party Deck, as the name suggests, is a deck that utilizes a technique called 'Mad Party'.
Mad Party is a skill that deals 20 damage * the number of Pokémon with the same skill as Trash!
Four of them have a Mad Party, Parbit, Galar Maim Kongkong, Fort Death, and Dedenne.
You can use up to 4 cards with the same name in your deck, so you can draw up to 300 damage.
Dedenne and Parbit have no special features, and Parbit has a low cost.
There seems to be an advantage that there is no type, so it is less affected by matchmaking ㅇㅇ
Fort Death can bury 1 Mad Party Pokémon from their hand in the trash and draw 2 cards!
It seems to make the damage increase of skills a bit faster.
Also, mime kongkong can change the opponent's prize and deck.
Hisui's heavy ball, etc. can reverse the prize changed by the opponent, drying the opponent's hand.
And in this metamon, you can use all the basic Pokémon's moves in the trash! lol
In this way, the maximum damage that could be extracted became 320,
You can now bury all of your Mad Party Pokémon without having to leave them for attack.
Mad Party Pokémon have different skill costs, so you don't have to worry about that lol lol
The fact that Trash's monsters' skills can be used seems to fit the Mad Party very well.
Metamon seems to be able to be used in Mildeck in combination with Iant, etc.?
