>>28763301I always reccomend people to get pic related when they are starting out in Standard.
They dont all go in all the decks but they are the base of every current standard deck.
2 Shaymin
1 Escape Rope
1 Super Rod
4 Trainers Mail
4 Ultra Ball
4 VS Seeker
2 Lysandre
2 N
4 Sycamore
2 Float Stone
These go in ALL of my decks no matter what.
If the deck is EX heavy (most of the decks in the format are) I add a copy of Hoopa.
Then I either chose between adding 2-2 Garbodor and bumping Float Stones to 3 or adding 2 Hex Maniac.
If the deck doesnt run 3 Float Stones and has many tech mons with heavy retreat like Regirock then I add a couple of switches.
If the deck discards many energies like Volcanion-EX or Greninja BREAK I add a copy of Fisherman.
If the deck runs megas I add a copy of Skyla.
If the deck attackes uses a basic + dce like Xerneas or damages depending on the ammount of energy like Yveltal-EX and Mega Mewtwo-EX then I add 4 DCE.
Stadiums vary too much to suggest a specific one. Fairy Garden, Faded Town, Silent Lab, Forest of Giant Plants, Rough Seas, Scorched Earth, Sky Field, Shrine of Memories are all useful. Decks ussualy run 3-4 copies of them or 2-3 copies + Delinquent.
Owning this cards will make deckbuilding easier since once you decided and get you main attacks and tech mons you will only have to get a couple of rogue trainers (like hammers or ffb) to finish your deck.
