What is a comp in Hearthstone Battlegrounds?

A comp — short for composition — is the seven-minion board you are trying to end the game with, plus the hero and trinkets that make it work. Most comps are built around one tribe, like Beasts or Murlocs, or around a mechanic like Battlecries or Deathrattles. The builder here is for laying one out slot by slot; the community page is for seeing which comps other players are actually winning with.

What is the best Battlegrounds comp right now?

There is no single best comp — what wins depends on your hero, the tribes in the lobby and the trinkets you are offered. That is why this site shows what players are sharing and how it is voted rather than one fixed answer: sort the community comps by upvotes to see what is working after the current patch, and check the patch diffs for what just changed.

How does board sharing work?

Hit share in the builder and you get a short URL. Anyone who opens it sees your board — minions, trinkets, hero and your build notes — plus a view counter and up/down votes. Nobody needs an account to share or to view.

What are Signature Mechanics?

Some heroes have card sets that only appear in their games — Jim Raynor's Battlecruiser upgrades, Sire Denathrius's Quests, Tickatus's Darkmoon Prizes. Each of those heroes has a page documenting the full set.

Who writes the hero and minion guides?

Players do. Any visitor can submit a tip, a synergy note or a correction from the card page itself, no account required. Submissions are reviewed before they go live, and contributors are credited.

Built a board? Take it with you

Write the comp up, then send it wherever it needs to go. Boards you are still working on stay saved in your browser.

Build notes
Write the comp up next to the board — how it opens, what to look for, when to pivot. Headings, lists and quotes all work, and dragging a card into the text turns it into a live card link. Notes travel with the link and the embed.

Every patch, compared

All patches

When a patch lands, the whole card pool is diffed against the last one — every minion, hero, trinket and spell that was added, removed or had its numbers moved, down to the individual stat. The history runs back to release.

Heroes with their own card sets

A few heroes bring cards nobody else will ever see. Each one has a page with the whole set laid out.

The guides are written by players

Every hero and minion page takes submissions — a tip, a synergy worth calling out, a correction when something here is wrong. There is no account and no form to fill in beyond the text itself. Submissions are reviewed before they go live, and whoever sent them gets the credit.
