Honorable Mentions: Surprisingly, during the So Paulo regionals, one of the top 8 of the event, Thiago Giovannetti, used a deck based on the Whimsicott-VStar line, which surprised everyone and made the card valued, before being considered a meme card: Whimsicott-V (Brilliant Stars 65/172) Whimsicott-V has 250 HP, Psychic-type, weakness to Metal-type, no resistance, for an energy as a retreat cost, and has two attacks (one of which is VStar): Trick Wind (for one Psychic Energy and two Colorless Energy) based on 160 damage, and during your opponent's next turn, they won't be able to play Item Cards or add Special Energy from their hand to their Pokmon
