Gentry is a budget Constructed format for Magic: the Gathering based on Standard. It was designed to allow everyone access to a constructed environment with a comparatively low financial barrier of entry.
Are you interested in making a deck? The rules are simple:
1. You are only allowed cards that appear Kaladesh, Aether Revolt, Amonkhet, Hour of Devastation, Ixalan and Rivals oif Ixalan). These are the Standard legal sets and should be available in-print in any store.
2. Your main deck has to have at least 60 cards, your sideboard can have up to 15 cards.
3. You are allowed a maximum of 15 Uncommons
4. You are allowed a maximum of 4 Rares and/or Mythic rares in your combined maindeck and sideboard that have to be individually different.
The fourth rule is what makes this version a lot more budget friendly than regular Standard. Not only does this make it cheaper by reducing the number of expensive cards you can play, it also makes most expensive cards less interesting.
Attention: The Planeswalker decks are legal as well and feature a set of important cards for Gentry at common. These are Cinder Barrens, Forsaken Sanctuary, Foul Orchard, Highland Lake, Meandering River, Submerged Boneyard, Timber Gorge and Tranquil Expanse, they are a set of nonbasic lands that produce two different colors of mana but enter the battlefield tapped.
The power level of Gentry is that of awesome Limited decks clashing across different sets. Try it out and let us know how it went on firstname.lastname@example.org or in the comments on this site.
