In no particular order, here is what I would consider meta decks: Regidrago VSTAR Toolbox (usually with Garbodor) Lugia VSTAR / Archeops with Double Dragon Energy Palkia VSTAR Shadow Rider Calyrex VMAX Stall, usually focused on Wobbuffet [Phantom Forces] or Snorlax [Pokmon Go] Fusion Strike decks, either focused on Mew VMAX, or Turbo Meloetta (with Dimension Valley) Of course, you then have other archetypes like Lighting stuff, Dark stuff, Arceus & Dialga & Palkia-GX / Dragonite V, Tsareena V, etc
The idea is to lead off with Smeargle from Reviving Legends [L2] and its Pok-Power of Portrait which functions as a de facto additional Supporter card
Join her quest to save the Realms with a deck thats ready to play right out of the box and experience Magic: The Gatherings most popular multiplayer format
Throw in a strong sacrificing theme, and this deck is great for getting a player used to how winning a game isn't always just about attacking whenever possible
END STEP Blood Rites is a great precon
Fountain of Youth could be used in very grindy decks that want to trigger cards like Drogskol Reaver or flavorful Jodah, Archmage Eternal lists
