What do you think will be the best/highest value cards in Burning Shadows?

Disregarding the obvious such as the secret trainers and energies, which Pokémon will be widely considered the best in this set? When I crack open packs what should I get the most excited about not having to buy a single of? I only collect so idk which cards work well in the game, so any help would be appreciated.

GR had Lele, Sylveon, and Ninetailes as the top 3 SM had Solgaleo and Lunala as the top 2

So who will be the best in this new set? I'm assuming Zard for sure. But who else?
