Lapras

Assist is a handy attack that lets you search your deck for a supporter card. You can use it to get whatever supporter card you need at a particular time. Hypnoblast not only does damage but also makes the defending Pokémon asleep with a successful coin flip. This Lapras has weakness to Metal Pokémon. Fortunately there aren't a lot of Metal Pokémon. That makes it a good addition to a water deck that has lots of Pokémon with weaknesses to Lightning or Grass.
