Hello, i paired magikarp with wormadam to youse weakness to win. The main strategy is to play an normal magikarp ditto deck but if your opponent has weakness to grass, fighting or metal you can attack with wormadam and if you have also supereffective glasses attached to your wormadam you can do a lot of damage with it. The peonia is think to get the right wormadam if it in your prizes. With pokéStop you can discard pokémons and get more items. Pumpkaboo is very important if your opponent play temple of sinnoh.
Let me know in the comments wat you think about this deck.
Have a nice day :)
