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 one from my friend (first picture ) were full texture foil, with texture on the image too
However, if such a creature can't attack players other than you, it must attack you (unless you control it) or a planeswalker or battle it can attack
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
If you chose Nessie: 20% chance to just search a new Danger to replace the discarded Nessie
Fountain of Youth could be used in very grindy decks that want to trigger cards like Drogskol Reaver or flavorful Jodah, Archmage Eternal lists
