New plane, new characters—naturally, Magic's inaugural trip to Kaladesh brings a lot of firsts to the game.

Here are five words you'll want to know heading in:

1. Energy Counter

What it is: A lot of cards in Kaladesh produce energy counters, which players accumulate as the game goes on and spend in order to enable various abilities. For example, take a look at Aethersquall Ancient:

Why it matters: Players will need to keep track of their energy counter total at your events. They can do that with dice, these printable tokens, or some combination of the two. We recommend having both on hand.

2. Planeswalker Decks

and

3. Bundle

What they are: As we announced in May, Kaladesh brings two new products to the mix. The first is an introductory product and the other is for more engaged players.

Why they matter: Going forward, these two products will accompany each Standard-legal set (Intro Packs and Fat Packs will not).

Planeswalker Decks are the best first purchase for players with a basic understanding of Magic, but its features are meant to appeal to experienced players as well. Each deck is ready-to-play with sixty cards including one Mythic Rare Planeswalker and a host of cards that synergize with it.

The Bundle is for players looking to dive right into the new plane, with ten boosters to help update their Standard decks, plus a Player's Guide with info on key characters, settings, and every card in the set.

Note also that Kaladesh triggers a Standard rotation—Magic Origins and Dragons of Tarkir are out.

4. Inventor's Fair

What it is: The setting for the narrative of Kaladesh. Chandra and Liliana arrive on the plane during a tremendous Inventor’s Fair, surrounded by ingenious discoveries and innovative machines. Optimism abounds—and obscures a nefarious agenda behind the scenes.

Why it matters: The story is a key selling point. The vibrant setting of Kaladesh is a breath of fresh air—especially coming out of the dark, warped world of Innistrad.

5. Aether Calibrator

What it is: An artifact from the Kaladesh Inventor's Fair at PAX.

Why it matters: We're giving it away, along with other real-life Kaladesh inventions from our set at PAX.

Until October 23, we're challenging WPN members to Invent Your Store's Tomorrow. Your interior, your event suite, anything you can imagine—take inspiration from the genius artificers on Kaladesh and find a creative way to innovate your store, then tell us your story. Four winners will receive a real-life artifact from our Kaladesh Inventor's Fair at PAX.

Got an idea you've always wanted to try? A renovation you've always wanted to make? Now's the time.
