The water frog Ash uses, can’t recall the name
Any furry Pokémon (Loppuny)
Honestly, Rayquaza. Cool legendary, but I still don’t get the hype.
Rayquaza has one of the rarest cards, the best meta pokemon to exist, only legendary to reach the top 10 list on the popularity poll, multiple grail cards in multiple languages, 1v7 against legendaries and held his own, only pokemon that can mega evolve without a mega orb, one of the best shinies and mega shinies and almost every single set its been in has been considered to be a top tier set.
Umbreon
Still not impressed. Like I said cool pokemon, but still overhyped.
I can’t even think of 20 pokemon that have higher feats.
Whatever the next one to have all its cards go up by a lot
Umbreon.
Rayquaza is just the copy-paste oriental dragon design that every franchise gets
Thats Charizard.
Gyarados.
How dare you
